Cycle changes after m/c

Spec
Hi everyone,
I have been told I have PCOS, but my symptoms are mild. 
The earliest I have ever ovulated is CD22, but it's usually much later. 
I did manage to get pregnant, but unfortunately misscarried. I'm now on CD8 of cycle 2 since the m/c and I'm starting to show signs that I'm gearing up for ovulation, with the app predicting peak fertility on CD14.
Is it possible that my pregnancy/miscarriage have 'reset' my hormones?
