Scarleteen

My boyfriend had already ejaculated but wiped it off and lay on top of me but both were still wearing long pants and underwear. I thought I couldn't be pregnant but after 2 weeks I felt nauseous but couldn't vomit and got my period in a few days but there were no signs. Could I be pregnant?

Hi Iamie_28,

Nope, you cannot have become pregnant from this incident. When there's at least one layer of clothing present, let alone four, there's no chance of sperm being able to get through into the vaginal canal. If you're still feeling anxious about this, I suggest going through this article and following the steps it recommends based on your specific situation: The Pregnancy Panic Companion

I have almost all the signs of pregnancy, including a missed period, so I'm very worried (

That doesn't change the fact that there wasn't a risk in the first place. Too, a lot of what we think of as "pregnancy symptoms" can actually be cause by a number of other things, and you can read more about that here: Chicken Soup for the Pregnancy Symptom Freakout's Soul

As a next step, can you go through that link I sent you in my first answer and follow the steps it walks you through? We designed that specifically for people who are worried about pregnancy and need to figure out what to do about those feelings.

So even if he has precum or has ejaculated, semen absolutely cannot get through 4 layers of pants, right? I've been so panicked lately, thank you very much!

That's correct, yes. You can read more about why that's the case, and what's actually needed for a pregnancy to occur, here: Human Reproduction: A Seafarer's Guide

Oh and still with those 4 layers of pants, but if my underwear inside gets wet from my sebum, is there any risk?

Can you go back and read those articles I've linked to you so far? There are answers to your questions in all of them.
