i’m almost positive i had a miscarriage. i’m 16 and i was like two months late on my period. i took pregnancy test once before my period was to come and a week after i was supposed to get it. both tests came out negative but i wasn’t buying it. i FELT pregnant. i was extremely tired and moody. i got sick once. and my boobs were tender. after 5-6 weeks i started feeling really bad cramping. my period cramps are not bad and can usually push through them. these cramps,however, had my bent over in pain. i want to the bathroom and wiped and noticed blood. i saw a sack like thing in the toilet along with some blood clots. my period is generally pretty light and lasts about five days. this bleeding was very heavy and only lasted 3 days. what is going on? i’m so positive i had a miscarriage.
