Just paranoid I think!!

ok so feel free to judge because if I get my period I'll definitely judge myself too but I'm just a little paranoid ya know!! ok so when my boyfriend and I have sex we use a condom and even tho we use one he still pulls out too. On NYE we had sex and since it was my last day of my period I check to see if I was bleeding, stupid me. I say stupid me because even tho my hand was dry, there could have still been sperm on it right? which means I could probably be pregnant? I know is this sounds silly but I have a cold this week and I read a cold is a sign of pregnancy://
