so for birth control im on the shot. after 3 months i was suppose to get another shot but i never went. so i got my period and i figured by me missing the next shot that caused me to get it. i had my period for like a few weeks. then it went away for a few days. i had unprotected sex and the next day i got my period again. even when i dont have my period im constantly bleeding like brown stuff. i dont think i could be pregnant but im just not too sure. or if im having all of this happen due to the fact that i missed my next birth control shot. can you help me figure out what could be wronge please ????

Hello, and I hope I can help you today. First, if you are late for your shot and have had unprotected sex, even if you are bleeding, you should do a urine pregnancy test. If your pregnancy test is negative, many women do not have regular periods come back after discontinuing the depo-provera injection for even up to 6 months.  This, however, does not mean that you cannot become pregnant.  If you are not actively trying to get pregnant, a good way to help regulate your cycles until your own body resumes a regular cycle is by taking birth control pills.  Birth control pills make you get a light, regular, predictable cycle every month and will help control breakthrough bleeding (the brown staining you have all the time).  Many women have irregular bleeding in the first 6 months to a year of using the shot, and unfortunately the same thing can happen after you discontinue it. So, in summary, all the irregular bleeding you are having is likely due to your discontinuing the Demo shot.  If you need contraception, the monthly cycle birth control pill would be a good option that can also help you have regular cycles. I hope I was able to adequately answer your question today and that my advice was helpful. Best wishes,
