I am a 22 year old that is sexually active. I was diagnosed with PCOS about a year ago after passing a blood clot the size of a grape fruit since then randomly I will pass blood clots, but they are not quite that size. Tuesday I started my period and it has been heavier than normal. I am passing about 7-8 clots a day. but tonight in the last 30 minutes I have had about 10 clots pass. I can feel them falling out of my body and they are about the size of 2 or 3 grapes. Should I be concerned?
