Getting ready to TTC again, but...

Meredith • Mother to my rainbow baby girl 10/21/16 and 1 on the way due 1/4/19 🌈🌈
AF is missing in action! I had a MC in November (my 3rd) and it passed naturally - got my period back in about a month but now it's been 35 days since then. I have always been regular. Negative hpt - anyway, My OB gave me some progesterone to take this cycle and I will be taking baby aspirin. But I have to wait until after my period. Thoughts?
