I had sex, when I was on my period, it was my second day but I know my body and was not bleeding that much that night so I thought it was okay. I read there is a chance you can still get pregnant if you have sex while on your period. I was spotting 15 and 17 days after this night I had sex. Do you think I should take a pregnancy test or wait and see if I have my period, which is suppose to come in about 7 days?
