im 13 weeks pregnant, had a heavy bleed early hours this morning and passed a big clot (what i thought was the baby) went to the hospital, bleeding stopped but still a little pain, had a scan and the baby was still there?! heartbeat as well.. they said i had a 4 cm bleed at the back behind the placenta, this was proabably becuae my placenta looks a bit rough around the adges but otherwise fine? I still dont really understand any of this and is it likely i will misscarry?
