MMC 7 weeks

Hi ladies, I’m at a loss right now as this is my first miscarriage and any information would be much appreciated.

Last week I was my OB where we found out I had a blighted ovum that stopped growing at 7 weeks (was supposed to be 10 weeks). Two days later I started getting excruciating cramps but was only spotting and passing some tissue. Since then I’ve passed more tissue but now on day 3, I’m starting to bleed and the horrible cramps are coming back.

I’m going to ask my doctor about it obviously and I know it’s different for everyone, but how long should I expect to bleed? I thought the worst of it was over two days ago but now I’m not sure. Any advice would be appreciated! Thank you!
