ok, I had my period on the 28 of november and it lasted until the first of december ( a little shorter than usual). Before the onset of my period and right after, my fiance and i had been having unprotected sex, however the the last time we had sex was december 2nd. About 5 days ago I noticed blood down there, it wasn't much, just pinkness. It lasted for about 2 days then turned brown..now its gone. I also noticed really bad pains in my very lower stomach/uterus area while jogging the other day (but that might be because i never jog lol). The blood has been gone for about two days now, but has been replaced with slight cramps (like i'm about to start my period but i know im not because i just had it!). So any insight would be nice. Thank-you so much!
