well for the last 3 months i have been getting these horrible pain in my left side above my pelvis bone. Ive also gained about 15-20 lbs and i have been having a heavy irregular period more often then usual along with spotting. I have ahd 2 daughters since 2007 and had an IUd put in in 2008. is this normal i havent changed my diet and ive actually become even more active then i was. im getting kind of worried as its not going away any ideas what this could be?
