So, the OB said even though the babies weren't growing anymore, that the hormone levels would not drop
until the tissue was either passed or removed. (I had spotted blood
, had a U/S, found out there were no HBs) I had a horrendous MC last Nov @ 14 weeks. To avoid that, I opted for the D&C. So, back to your question. The D&C is like a system reboot. It resets your cycle to zero. So, your new cycle has nothing to do with your LMP date.
