So my ex girlfriend just alled me and she told me she thinks she's pregnant. The last time we fucked was about 2 months ago and she told me that she hasnt had her period since. But she's saying that she knows she either had her period a week before or a week after we fucked.

My question is this: what is the likelyhood that she had her period a week after and hasnt had one almost 2 months later without being pregnant?

If she had her period before you fucked, she's probably pregnant. That, or she just missed her period due to stress, malnutrition, or whatever. Two months is enough for a girl to figure it out without a pregnancy test. Is she throwing up all the time?

If she had her period a week after you fucked she's not pregnant. Go buy a pregnancy test and stand with her in the bathroom while she does it. Then you'll know for sure if she's lying and/or pregnant. I suggest a DNA test if she really is pregnant: http://www.youtube.com/watch?v=8Pi_9j65Gvk

But is it likely for somebody to go almost 2 months without their period?

Well you need to see if: 1) she's even telling the truth. 2) if she is telling the truth but not pregnant 3) if she's telling the truth and pregnant 4) if it's yours.

But yeah, it's fairly common for girls to miss periods. Does she do a lot of sports or physical activity? Is she under a lot of stress? Does she have a weird diet (not on a diet, I mean what she eats regularly)? Has she started a new medication or gotten off of an old medication?

Try google if you want more scenarios. It's really not that uncommon for a girl to miss. Oh, did you use a condom and/or is she on birth control? I should've asked that to begin with.

Like I already said, you need to find out if she's pregnant first. Then if she's not you can figure out why she might've missed her period. You're wasting your time if you don't get her tested first.

and this: If you've not had a period for two months make an appointment with your GP and remember that ongoing stress often causes your period to stop for six months or more.

Ok well here is the scenario. I put on a condom and we started fucking and a tiny rip formed near the opening, but that was literally within seconds of when we started, which i dont think would have been enough time for even any pre cum to come out. Once I noticed that I imediately pulled out and put on another one and resumed. Then about a minute later she started crying (thats another story) so I decided "fuck this" and we stopped. I checked that condom later and there were no rips in it. I didnt cum, either.

And no she wasnt on any birth control.

Edit: Shes getting tested tomorrow.

There's basically 0 chance of her being pregnant. Precum is really ineffective for causing pregnancy, that's why semen is full of millions upon millions of sperm, and that's why it needs to be ejaculated far up into the woman. If you noticed the tear early on, pulled out, put on a new condom, and then stopped before ejaculating, there's pretty much no chance for her to be pregnant.

I'm glad you're getting her tested though. If she's not pregnant, which is what I'm guessing, then it's probably stress or some other factor and she should see her doctor just to be sure. I'd get some sleep and not worry about it. It's extremely unlikely that she'd get pregnant from that scenario.

Alright thanks a lot for the links and the suggestions. I read some of the links and I think I may have figured out why she missed her period. That took a load off my mind.

Glad to have helped. I've been in the whole 'girlfriend missed her period' scenario and it totally sucks. Based on what you told me, you really have nothing to worry about. Just get her checked for pregnancy and then to the doctor to make sure nothing more serious is going on.

And sadly, you probably don't need that 'dat baby don't look like me' video link :/

During the first few weeks of pregnancy there can be a bleeding which can be mistaken for a short period.

I know because it sure fooled us!

And from that you've said about the condom stuff - if she is pregnant, you're most likely not the daddy.
