I believe I may have contracted the HIV virus. I was in a pool with a significant other, this was the first and last time we engaged in sex, kind of he inserted his penis about halfway but then pulled out because a friend came to the pool. About a week later I got a yeast infection, after that stopped about three weeks later I wasn't feeling well had diarrhea trouble sleeping and slight night sweats. I also got my period two weeks early, but didn't think much of it because I moved into a house with two girls and we synced cycles, I have also had abnormal discharge slight itching, and dryness. is it possible for me to ha e contracted hiv?
