<s>[INST] i ve been on the depo shot for 6 months and on the pills for 3 months after starting the shot in december i started seeing this dark brown color and sometimes i d cramp a lil and bleed or have spotting alot with the dark brown color. I ve been getting tested while this has been going on and don t have any signs of a trasnmitted disease. I also had to start taking vitamin pills last month because my vitamin level was off and wanted to know if these are effects from being on birth control [/INST] Hello mam, thanks for trusting Chat Doctor. In my opinion do a urine pregnancy test which is negative get a pelvic ultrasonography and b Chat Doctor testing because it can be an early pregnancy or worse ectopic tubal pregnancy and then visit a gynecologist with reports In case you have further questions you can consult me on Chat Doctor forum and I will be happy to helpmate care and wish you all the best.
