I’m 15w pregnant and on Monday I woke up bleeding like period so I went straight to ER and they check if baby was ok with a scan and everything looks perfect, heartbeat and baby was moving but still bleeding. After lots of question an urine check they check with a speculum and shows white tissue protruding but they said unknown nature of tissue. They send me home reassuring that baby was ok, placenta ok and cervix was closed. They also told me that this could be a polipo, a twin pregnancy never developed or a cystic. now I went to wee and this white thing came out of me. I call the day assessment unit ant they told me not to worried that the bleeding should stops now. Anyone had this before?

Any advice is welcome.
