When i had my miscarriage i bled for 2 weeks but everyone is different which you know. It depends on your body
I lost my baby on tuesday...It's thursday now...and I'm still bleeding. I had cramps all day tuesday and wednesday. The blood flow has calmed down some for me. It really just depends on your body. After my D&C last time I stopped bleeding around a week and half. My other miscarriages I went a normal cycle about 6 days. So depending on your body. The doctor also told me today that you stop bleeding when you hcg level is back at 0.
My doc told me that it just depends on how far along you are when you miscarry. The first time i miscarried i was 17 weeks and i bled for about 1 month thereafter. The time before last I was pregnant for 4 weeks and bled for about 1 week. It all depends on your body and your conditions. You can expect anywhere between 4 days +. I know this isnt much help but this topic is iffy.....I am so very sorry for your loss.
