I haven't had a period in 3& 1/2 months. I've had numerous negative hpt & 3 negative blood test back in June. I've developed chronic heartburn & severe weight gain.. my nipples have even become sore here recently... since being told that my tests were negative I had been participating in activities frowned upon when pregnant. I occasionally get back pain.. so bad once I thought I had kidney stones but when I went to the hospital they said all was fine: no uti, no yeast infection, or kidney stones. This month (August) I have been cramping like I'm going to get a period but nothing... I sleep all the time anyway so I don't know any other way I could tell haha. I no longer have health insurance so I can't go to an obgyn & I went to my local health center & they said I'm fine its just the because I was on... yet I was on the because for a yr starting in 2010 always had a regular period before & during & after the shot. I discontinued it in August of 2011 & still got monthly periods so I started it again in February but stopped in May & did get a period. That was the last period I received... any idea what's going on.?
