I have been on birth control (depo) for four years , ive just got off of it six months ago i ididnt have my period the whole time i was on it but i started my period last month it was norma, now i started again an it wasnt normal i went to the bathroom an wiped it was spots of bright pink blood on the tissue so i thought i was going to have a normal period but instead of red blood coming out it was brown and it wasnt heavy and lasted for 3 days, i had no cramps , no sore breast or nothing , o and im 20 years old, i have one child. Its been four years since ive been pregnant and when i was pregnant i didnt have ANY symptoms. im very confused so can someone please help me. Ive looked all over the internet an all i see is pregnancy and stuff about menapause.
