Well I had started my period on the 6 of September, but my period happened to be lighter. Couple of weeks later I' am getting weird symptoms that are signs of pregnancy. I've been feeling bloated, constipated, craving sweets, and going to the bathroom more than usual. However, me and my boyfriend did not have sex, we just fooled around. Could the semen have accidently gone into my vagina, and caused these symptoms?
