TTC after a D &C

Amy Jo • 29, married to the love of my life, mommy to an amazing baby boy 8•11•15, now expecting #2 in April ❤️
I had to have a D&C July 30, because my progesterone levels dropped drastically. I was 7 weeks pregnant. My doctor put me back on BC and wants me to wait 3 cycles before trying again. I'm ready to start now. Has anyone started trying sooner? I would really like to start after my second cycle but I want to make sure it would be okay... Advice please ?
