About 7 months ago I had a miscarriage my monthly period has been crazy since the miscarriage I've had 1 normal period. Last month I spotted for 28 days... About 3 days ago I started my period and it's been heavier but I expect that due to the fact that I haven't had a typical period in awhile well tonight I had a rush of bleeding and on my pad was pretty big bigger than I've ever had clots I'm just wondering if this is normal or if I should be concerned???
