Hey, i had sex on the 21st march, it was unprotected, he pulled out before he came, hes been circumcised too, im a few days late on my period, im worried i could be pregnant!!! I think ive put on weight, but this could be my periods because i always feel fat when im about to come on! I also have a few spots that have come up which also usually happens when im about to come on my period!! I took a paracetamol overdose at the start of march i had 24 tablets and was in hospital for one and a half days before i was discharged from the hospital! could this affect my period???
