Can I Be Pregnant From Pre-Cum?

Here’s a question from a reader who is worried she is pregnant from pre-cum, but I have other worries. This post contains references to sexual assault and non-consent, so be careful before you read any further. 





I’m 16 years old but I left school already…. My situation is that I was messing around with my boyfriend and he tried to push his penis inside me. It didn’t go in and it hurt a lot and he was only there for a few seconds and I told him to stop. And I asked him what if I get pregnant he said I won’t so I asked him if he precumed he said if he did he would know. I told him that guys can drop semen without knowing, he said yes he knows but he would’ve known if he dropped so much. And my period is supposed to come next week Friday. And I don’t know what to do.


Thanks for your question. I’ll answer your question first but there’s something else I’m much more worried about.

Pregnant From Pre-Cum?

So it’s incredibly unlikely that you will be pregnant from what you describe. The average chance of pregnancy for one time sex is 3.1%. This is between 0% and 9% depending on whether you were about to ovulate or not. However this is with someone’s penis fully ejaculating inside someone’s vagina, which is not what happened with you. You can read more about how pregnancy starts and where I got those figures from about pregnancy chances here.

There is a possibility that there may have been enough sperm in your boyfriend’s pre-cum but it would be rare for there to be enough mobile sperm for pregnancy to occur. And even then the pre-cum would have to have happened with his penis being fully inside the vagina. I wrote about pre-cum here and have just updated it.

So I’d be amazed if you are pregnant from this. You could go and chat to someone at a sexual health service if you think you are at risk. You could also chat to them about contraception. I think there’s some other stuff that you could be chatting to them about too though.

What Worries Me

Your description of your boyfriend trying to push his penis inside you made me feel sad and worried. You told me about it but you didn’t say you were concerned about it (at least not directly). He really should not have done that because it sounds to me like you didn’t want that to happen. This is serious business and, if the police got involved, he could be questioned about, or charged with, a sexual offence (like rape, attempted rape or sexual assault).

What he did was wrong and that you shouldn’t have to put up with him treating like that. When it was happening, you told him to stop and he did. He should have been aware that you were not into this before it got to the point of you saying stop. It’s not cool to put someone in the position of having to say stop, or no. This is on him, so maybe he should be reading this website about how to do consent better.

Sadly this is really common (with one in ten women reporting having had sex without wanting to). However I also don’t want to tell you how to feel about it, that’s not my job. Your body is your body and your feelings are your feelings. I’m not here to tell you what it is that you should be feeling, thinking and doing.

If you are chill about it and you have told him that wasn’t cool and are confident it won’t happen again, then good for you. If you wanted to dump him because of this, that would be totally legit. Also if you wanted to tell someone else about this and ask for their help that would also be good. You could report this to a Sexual Assault Referral Centre if you wanted to, they could give you some help and support. You didn’t leave an email address but if you want to get back in touch with me I could try and help you find a service near you where you could get help, if you wanted it.

It’s your call how you deal with it, I just want to get you to think about it.

Hope that helps

  1. can pregnancy occur if my girlfriend has sex on the first day of her period and i did not ejaculate and only precum was there ? she has an irregular cycle (39 -50) days cycle . I read online that if someone has irregular or unpredictable cycles they can ovulate as early as day 6 of their cycle.
    we had sex on day 1 of her cycle ,her period lasted for 4 days . even if there was sperm in my precum it would not be viable until day 6 ( if she ovulated early ) . so what are the chances of pregnancy happening from this event ?

  2. My bf and I were fooling around and we dry humped , he wore 2 layer of underwears but I didn’t wear any, but he did kinda pre-cum , and had a wet spot on his shorts. And I had my last periods exactly a month ago, I’m a day late.. Is there any chance that I am pregnant?

  3. Hi, me and my boyfriend decided that we wanted to try having sex but it was difficult to fit, and he didn’t ever fully go inside me, only barely the tip. He 100% did not cum. There was pre cum but it seems like there is a very low chance of getting pregnant from that. My problem is that I had my period around 5 hours after we had “messed around.” It was my normal 4 day cycle, I have a very irregular period and im unsure if im currently pregnant. Thank you so much!

  4. Chances I can be pregnant from precum? Had unprotected sex on Dec 30. He didn’t cum at all. It is now Jan 25 with a missed period that was supposed to start Jan 20. I’m a 16 year old. Could it be the stress of thinking I’m pregnant making me miss it? I have also recently started exercising after years so maybe from exercising? Could it be it being my first time & he was little rough? When I say he was being rough I mean my stomach hurt 3 days after the sex. Do you think being on antibiotics it could mess with my period? Sorry I got so many questions. Very worried.

  5. I just touched my penis with my girlfriend vagina and I dont know that I got pre cum after that she had her normal periods after two days. Will she will be pregnant and we did not had any intercourse it’s just touched two times.

  6. Is there a chance that I will be pregnant if we had unprotected sex on my first day of period? He didn’t cum inside me because he just tried to get inside for a few seconds just to feel what’s inside if i had my period, but I’m worried because he masturbated before. Is there a chance that there’s a sperm in his pre cum? Thank you and I hope you reply asap.

  7. My girlfriend has her menstruation, but we had sex, but i as the male, did not ejaculate, and we only did it for almost 50 seconds, more like a minute for a minute or two. Also she’s an irregular, a super irregular one. her periods usually comes after 3 – 4 months. Her previous period was on Feb 18 2019, We had sex on June 13 2019 and the start of her period was on June 10 2019, can she get pregnant,? If shes super irregular, and we had sex on her period, ? What are the chances? Please answer thanks

    1. I think if you re-read the article, and all the links I’ve provided, you’ll find the answer. Can I also recommend using condoms next time you have sex, and perhaps discuss the risks of sex between you before hand.

  8. I honestly wouldn’t post on this website if I wasn’t scared. Me and my girlfriend decided to have sex and a condom was absent from the equation. I want to know if I could’ve gotten her pregnant with precum. (I pulled out earlier as to not increase the chances). I didn’t masturbate earlier and went to the bathroom before in the day but I’m not sure if it’s still a high possibility. Thank you for your time.

    1. Can you please just read the article and the links in the article again? I’ve already answered your question. The average chance of pregnancy from one time sex with full ejaculation in the vagina is 3.1%. The average chance of pregnancy from one time sex with no ejaculation in the vagina is much much lower than that. Somewhere between 0 and 1%. If you’re worried about unplanned pregnancy then your girlfriend could take some emergency contraception which you can get from a sexual health service.

  9. Please do answer my question! My girlfriend is super irregular, she goes for 4-6 weeks without menstruating, her last period was in the month of January, and me and my girlfriend never really did engage in penetrative sex “fully”, we usually dryhumped and there were two-three instances wherein we tried pnetrative sex but never really did do it fully, it’s like just the tip of the penis inside her entrance for a few seconds, no ejaculation. My question is, could she be pregnant? her last period was January, until now her period is still missing. The last time we had our little session was around May 4. Please help, we’re both scared, and she should’ve practiced proper birth control

    1. As this article you are reading says, there is a very low chance of pregnancy from sex that does not involve sperm being fully ejaculated in the vagina. So it’s very very unlikely that the sex you are describing has started a pregnancy. As you know, periods can be super irregular and there are lots of reasons why that might be (stress is one of them). Finally, I don’t really see why you are putting the blame on her for not using birth control. You put your penis inside her, you could have put a condom on.

  10. Hi…so me and my boyfriend and sex….and the condom broke…but he didn’t cum…he said he did pre- cumed…I am stressing, I’m only 17…and is there any way I can fall pregnant or is there any way I can prevent it….I am on birth control been on it for 2 weeks…


    1. Hi Sarah. So, as I say in the article, there is a less than 1% chance of pregnancy starting from pre-cum being in the vagina. Also the condom may well have prevented much of the pre-cum getting in your vagina (depending on how badly the condom broke).

      Also you’ve already started using additional birth control, which means that you are at a much much much much much lower risk of pregnancy (think about it, most birth control methods are over 99% effective ). If you’re still worried then I would go back to where you got your birth control from and ask them to re-assure you.

      For the future, if you are going to keep using condoms and birth control (like the pill, IUD, IUS, implant, etc) then it might be a good idea to make sure you’re using condoms properly. They are more likely to break if they aren’t put on properly, if they get too dry, if they come into contact with something oil based like lipstick or moisturiser, or if handled by sharp nails.

      Hope that helps!


  11. I was inside my girlfriend unprotected for a few seconds before going back out.. I wiped off any precum on me before entering then was in for about 5 seconds . I’m worried she is pregnant as her period is 3 days late.. could she be? Isn’t there like a 2% chance of that ? I’m so worried..

  12. I’ve had my periods after dry humping but periods laster for 4 days and now there is spotting for almost 5 days. Total almost 10 days of periods. Could it be related to pregnancy?
