okay so last month i had protected sex with those trojan thin condoms, my period was like 5 days so on the third late day i took a pregnancy test and both were negative. the next day in the morning i took two more and they were negative. i was stressed out for two weeks prior, started going to the gym, a new job, and school started. i'm 17. when i got my period , blood didn't drip but it was heavy enough for a normal tampon and some clots came out. the cramps were horrible i couldn't move. then it stopped for half a day and then it came back very heavy with a lot of clots. i think i ovulated because i had the ovulation discharge i usually have but i am peeing more frequently but when i pee it's not a lot depending how much water i drink. my boobs had stretch marks but now they're gone. do you guys think i should worry? im supposed to get my period next week.
