Well here is my story i didnt receive a period for 2 months i was so mad because i wanted to have the mirena in place before my surgery. I had pregnancy test done several of times and they all came back negative. So i decided to take provera almost three weeks before surgery. after taking provera i still didnt get a period. I had my surgery on 4/25/12 i got my period the next day. I felt like someone gutted me open. my period ended one day after my first doctor visit which was 5/03/12. When i weighed in it showed i lost 8lbs when i know i lost more than that. Could it be that i was bloaded thats why it didnt show as much weight loss.
