Ovulation after miscarriage

Hey ladies!

Is it normal to not ovulate after a miscarriage? Or how long did it take you to ovulate again?

Miscarried July 25 at 6 weeks naturally (no D&C needed). My doctor told my husband and I to wait a month/cycle before trying again (technically didn't try but didn't use any protection). I got my first period again like clock work (32 day cycle) and it lasted 10 days! I am now on CD 19 and my OPKs are just not darkening at all! (I've been testing since CD 11)

My periods before the miscarriage were about 4 days (32 day cycle) and I would get a surge about CD 17/18.

Not sure if anyone has had this before?

Thanks in advance and baby dust to you all! Xoxo
