Hi, sorry to meet you here :(
After a mc, periods usually come back once hcg is back to zero.
@Countrygirl29, your hcg was 5 units three days ago, so I would assume that the bleeding you are experiencing now is likely to be your periods. And the hope associated with a new cycle starting if you want tor try again :)
@DappledOliveGroves, don't worry, they will return. But you could have some hcg left in your blood, which is why they havent reappered yet. But i dont think it should be long tbh.
Regarding the intensity, it all depends on how far you were in your pregnancy.
When i had a termination at 14w (hormones levels very high because it was not a mc, but a termination), it took 3 months for my periods (that were very heavy) to come back.
For my 4 miscarriages that followed, between 6 and 9 weeks, periods usually came back within 4-5w max, and the bleedings were normal.
Hope that helps, and take care xx
