I am 16 year old girl and i am very nervous i might be pregnant. I just ended my period about 2 weeks ago and i had sex twice without pertection a couple days after getting off my period. It feels like im on my period again but the bleeding is heavier and its more brown with clots. Im not sure what to think and i havent taken a test yet. I dont know if im having a miscarriage or what, but ive had some pretty severe cramps since then. Please help me, i am beyond scared. Thanks.
