My boyfriend and I have fooled around about 3-4 days before I was supposed to get my period. Today my period is already 3 days late and I am panicking. I gave him a handjob. He fingered me and we rubbed genitals for about 3 seconds, this was before he came. When he came, it didn't go anywhere near my vagina. He came from me giving him a handjob. After that we layed down for around 10 minutes and then he gave me oral. I may have had some of his sperm on my left hand (but I don't think so because I used my right hand), and I used my left hand to touch my clitoris. I have read many websites about this and I know there might be a small chance of pregnancy, so I am freaking out because my period never comes late. I have my period for 2-3 years and I am 15 years old. I know I am too young and this won't happen again. Please help me, could I actually be pregnant and is that why my period is late? I know it can be late because of stress, but I have only stressed today and yesterday.
