My name is Anna and i am sexual active, i had sex a 2 days before my ovulation and my boyfriend cum in me  and i took a morning after pill the other day and couple days after i have been having sex with condom but they burst almost every time but he didnt cum in me those time, alot of unprotected sex the last couple of weeks now i should have had my period on sunday aug 13 but it came two days earlier, i have been stressed all that time wondering if i was pregnant. So my period came friday aug 11 but something different i saw, my period normally red but this time it was dark brown with clots  on the pad and it was thin, it came like my period i had terrible cramps, i was weak and drizzy at he starts and it was alittle heavy but it came light and thin , it looks red when coming out of me but it is dark brown with clots on the pad. so i dont know what is the reason, i would like to know what u think it is could it have been my period because it came a could time anyhow i was stressed out pretty bad or could it have been implantation bleeding and i am pregnant or could it be other serious reasons. My cycle range from 24-28, average is 26 plz.
