Could I be pregnant?

[gemini12319]

I'm not being ignorant to sex ed or anything, just being cautious. My boyfriend and I were messing around the other day and I've been pretty nervous since. We were both fully clothed (He had on pants and underwear and I had on pants and underwear), however, when he ejaculated, a small wet spot soaked through on his pants, near my vagina. He got up and changed his pants immediately after this happened, but I'm still slightly worried. I'd rather be called an idiot for asking this than not know the answer. What are the chances of getting pregnant through 4 layers of clothing?
Any answers you can give me, I would greatly appreciate.

.000000001% chance. Don't even stress there is no way you would be pregnant.

None.
