question about positive preg tests and cycle starting up after mc

[Eggfrog]

Hi.
Does anyone know: does your cycle only start up once you test negative post-mc? (i.e. once all the HCG has left your body)
Or can you start gearing up for ovulation and even ovulate with HCG still in your system.

Just trying to work out where I am really. My suspicion is that the HCG must all have gone. And since mine was a mmc and I had an erpc, I'm concerned my body will take longer to realise, and therefore my cycle may be slow in returning.

Any advice much appreciated

No idea on any science-speak or theory behind it but I had two MC and both times period came precisely 4 wks afterwards as if MC had been normal period.

Your cycle can return before negative test, but it is usual for ovulation to be delayed slightly.
