I was diagnosed with pcos abt 11 yrs ago. Got preg on clomid, had a daughter 9 yrs ago with no probs, normal preg. Came off bc abt 2 yrs ago, had 3 periods since. Last one was in January. Started spotting two days ago, bad cramps last night, feeling of heaviness and pressure lower stomach. This morning felt like water bag burst, blood and fluid came out. Lots of blood and HUGE clots that looked like liver. Cramps have eased, still bleeding a lot, but much improved. I have not felt pregnant in any way. Have never experienced anything like this ever. Might I have had a miscarriage? Btw I am 37 and overweight.
