Hi doc on the 7th of august I had sex (protected) with my boyfriend right after the day my period ended I did not take any emergency pill after. My next period was supposed to be 9 days ago but on the 22nd I was bleeding approximately for the days my periods last on the 2nd day the bleeding was heavy with clots now what worries me my periods didn?t come the day they were supposed to now my tracking app says i?m late could I be pregnant?
