i was 8 weeks and 6 days when the bleeding started but according to my hcg levels the fetus was 5-6 weeks only..
I am sorry for your loss. How far along were you? I do know it takes awhile for hcg levels to decrease so it could be your hcg levels decreasing. At 5 weeks my hcg levels were 2 and I took a pregnancy test 4 weeks after my miscarriage and that was negative. It could be the hcg levels decreasing.
I think in these situations it is hard to know what is happening until you get proof. My cousin's partner miscarried and had bleeding, they couldn't find a heartbeat or anything and then 3 months later she was 5 months pregnant. It was a mystery as to why she had bled so much and miscarried yet another baby survived. It was very strange as she didn't know she was pregnant because she thought she miscarried. They think she was pregnant with twins, one miscarried and the other survived which is now a healthy 3 year old.
I think that miracles do happen but most of the time it is less fortunate news we hear. Good luck
