I was at my boyfriend's house, and we were playing around. I was giving him a handjob and he came on my hand. I don't think he got any sperm on his hands, but I'm not 100% sure. Then a little while after (maybe like 5 mins later) he fingered me. I touched my clitoris with the hand he came on(I'm pretty sure it was dry though). I'm really worried I might be pregnant, someone please help me. I'm 16 years old, and extremely worried. I don't know when I'll get my period, because it has always been irregular. This happened around 2 weeks ago, and I noticed my nipples are sore when I touch them.
