I have been on the depo shot for 2 years and as soon as I got the shot I stopped bleeding and haven't bleed scence. Until now, I have been bleeding for two months on and off everyday, sometimes its some wht heavy but not like a normal period and sometimes it's light to wear I can just wipe it away. Now I am also have stomach tenderness, any little pressure really hurts. I am taking a weight loss pill perscribes by my other doctor and the bleeding started two weeks after starting the weightloss pill. Could it be the pill? Is the pill affecting the depo to where it's no affective. I really need to know because I'm scared. Me and my fiancé had unprotected sex about a well ago and I started bleeding during and after really bad, now it has slowed down ALOT to where I almost don't have bleeding. And I have stomach tenderness now. Could I be pregnant? Somebody please HELP ME because I have a two year old and I'm not financially stable for another kid yet.
