No ovulation after miscarriage

jen

I had an miscarriage two months ago and my doctor ordered some blood tests . On my cd21 progesterone tests I was 2.6 and she said I am not ovulating and they don’t see why cause all my other tests are ok .

Could this be due to the miscarriage? My cycles were always 28 days and now for the last two days they been 38 . Can I not ovulate cause of this ?
