So on the 4th day of my period that lasted 6 days my boyfriends dick slipped and touched my vagina. I had a tampon in since I was on my period and stopped right after it happened. The bottom half of my vagina was dry and my boyfriend even blew into both my vagina and ass to dry them up (since he heard sperm die when they are dry). Is there a chance of pregnancy? Or am I just extremely paranoid over nothing?
