DD born in Dec 05. BF for four months. My last three periods have not been too heavy but they are extremly painful. Pains in tummy, lower back and even my backside. I've sat down a few times and had to jump up again because of shooting pains. I'm popping pain killers but they are only numbing the pain slightly. Never had problems before. DD born by c section, could this be why? Also find that on my ovulation days I feel like I have my period. Is it my body just going back to normal or should I be worried about it?
