Can I, a virgin, now be pregnant?

[ailsa9876]

Yesterday, my boyfriend and I dry humped where I wasn't wearing underwear but he was. He never came but he did precum quite a lot. He later rubbed the tip of it up against me when neither of us were wearing underwear. I don't know if there was any precum then. He never came at all.

I get my period around this time, I last had it a month ago today. they are not entirely regular due to constant stress right now (As you can imagine, this isn't helping). I am still having cramps, but it hasn't come yet.

I understand that what I have done is extremely stupid, and trust me, I will not do this again anytime soon.

So... Is there a chance I could be pregnant? If so, what kinda percentage am I looking at? I'm absolutely terrified right now.

It all depends on when you ovulate. Not all women ovulate in the middle of their cycle. Pre semen can get you pregnant but the chances are lower compared to your boyfriend actually ejaculating. And, it's so close to your period starting.That can make your chances of being pregnant even lower.
You have some options. You can take Plan B. It needs to be taken within 72 of unprotected sex. Or, you can wait for your period. It sounds like it's getting ready to start.
If you decide to take Plan B it might delay your period or make it come sooner.
I wish I could tell you there is absolutely no chance of you being pregnant but there is a very small chance.

Although there is a chance that you could get pregnant from pre ejaculation, I doubt that you are pregnant. Just try not to stress about it, wait for your period to come and if it doesn't come then take a test.
