I'm 14 years old and recently I gave my boyfriend a hand job. I've never been on birth control or anything like that. I wiped the cum off of my hand when he ejaculated. then after we held hands and stuff. it was about 2 hours later and I never washed my hands. the semen was exposed to air for that whole amount of time .. also cold air. when I got home I totally forgot about what happened and touched myself and inserted my fingers into my vagina maybe 3 or 4 times. it was the day after my period ended. on the 4th day after this incident I was so worried and scared I could be pregnant so I took plan b. is there any way I can get pregnant from 2 hour old sperm that has been exposed to air that whole time? I have experienced discharge but I always experience that even before this happened. also, my nipples have been red and I have gotten bumps around them. could that be from taking plan b and having that effect my body? my breasts do not hurt. I have been so worried about this whole experience. please help me if you know what you're talking about, thank you so much.
