Cycles after miscarriage

Would y’all mind sharing a few things after you had a miscarriage:

How long it took you to get your first period?

Did your cycle return to normal duration for your second period?

I had long cycles before my miscarriage after getting off birth control in March (40ish days). After my miscarriage It took me 6.5 weeks to get my first period. I’ve been doing opks and BBT and I’m on cycle day 19 with no ovulation and just frustrated that it seems like my cycles are going to be long again!
