Can having unprotected sex on the first day of periods cause pregnancy?
Patient: i have had unprotected sex with my partner during her first day of periods , the second day her periods stopped with few spots and her periods usually last for 3 days... today is her 3rd day and shes having cramps in her lower abdomen, what are her chances of her getting pregnant Doctor: Hi.. Thanks for writing.. If you had intercourse on the first day of periods there is almost no chance of pregnancy.. pregnancy occurs only when ovum is available..  So don't worry..
