Last month, my period came on & I had MAJOR abdominal cramps, pain in my back & hips & it radiated down my legs. (My tubes are tied going on 4 yrs now) My period was VERY heavy with major blood clots till the very end which was about 5 days. Since then, Ive been having hip pain & radiating pain in my legs still. During ovulating time, I always have pain in my ovaries as well. I took several pregnancy tests, all negative. What could be going on? Oh & Im 3 days late this month. Im always on time.. every 28 days.
