The last time I had my period it was from June 24 to June 29 2016. My best friend came home and we got together. I gave him a hand job but he came on himself and on my hand. I made sure to wipe everything off and so did he. I had a tampon in as well. Then I left for basic training a couple days later, then was medically discharged due to an allergic reaction. I hoping its just stress that's causing it. My friend and I are both in the military and it wouldn't be good for us right now if we find out we're having a baby and because we're at different parts of the continent. Any advise will help. Thanks!!!
