I've always had long (5-7 days) heavy periods but the last two months they have been short (3 days) and light, is this normal? Also I always feel left pelvic pain during the time I'm ovulating but this month it's more like a cramping (not as bad as it is during my period but close), I had a HSG last month and I wonder if that's why? I believe I'm ovulating today so here's to my TWW...
