Am not someone who has a regular period but I do see it every month it just changes its date. So this month had sex with bf on the 8th took morning after pill the day after. But we still have unprotected sex through out but usues the withdraw method but on the 16 he came inside of me so I decided not to take the morning after pill again cause I dint want it messing with my health. On the 17th I notice my nipple is sore whenever I touch them. We still has unprotected sex every day.I saw my period on the 20th of last month now today is the 24th and no sign of my period just light cramping and sore nipple when I touch them. Could I be pregnant or my period is just late?
