My mother decided to put me on the Depo my 8th grade year because I was dating a 17 year old boy. I was on it for about 3 years. My last normal menstrual period was in December of '08. I recently told my mom I was tired of birthcontrol and didnt need it, about November of '10. It's March of '11 and I still havent had a period, I didnt have my period, or really ever blot during the use of the Depo Provera, and I've taken tests to see if I'm pregnant but they've came out negative. Is this normal? When should I expect my period?
