Not ovulating after miscarriage

Shashikala

I had a miscarriage at 5 weeks in aug 2018. We took a break for 2 cycles as doctor suggested. Started taking ovulation tests with clear blue opk . All the tests are coming negative.

I see this only after miscarriage. Also my cycle length has become shorter (like 23 days or 25days)

Before miscarriage it was regular exactly at 28 days.

Has anyone going through the same problem?

Please advice
