Since it was so early, the Hcg would leave your system pretty quicly. Clomid may help o be a little sooner, too. It did for me. I know others that it delayed, but it did make me earlier. It could be a precursor for o. I o'd on cd12 one cycle on Clomid.
I'm not totally sure but I've heard it's possible. good luck with a new cycle!
