TTC 1 year. Miscarriage 1 year ago exactly. I passed a blood clot with minimal cramping last Friday and bleeding didn't last long. So I took a test on Sunday and it was posivite with in 10 seconds. Not 4 days later I have passed 3 more blood clots in a 2 hour span,with no cramping and now have stopped bleeding again. I am waiting now for a call back from my Ob nurse
