What are the chances?

I feel like I already know the answer to this question, but I’m going to ask it anyway to ease my anxiety.

My boyfriend and I were messing around and he came on my underwear/skin. It wasn’t near my vagina, like more my pubic area/hip, like the area between my hip and lower stomach. Lol just trying to paint a picture for ya! Anyways, it wasn’t on my vagina. I cleaned it off and just went to bed and stupidly didn’t change my underwear. I woke up and it seemed like that spot on my underwear was still moist. It’s also very possible that some of that moisture could have been lotion. What are the chances of pregnancy? Just want to ease my anxiety.
