Trying to get pregnant after miscarriage

I had an early miscarriage in the middle of November. I still have not gotten my period or ovulated yet?

I’ve always had irregular periods so i think it’s just that but i been testing my lh and keeping track of my bbt. Nothing is showing signs of possible ovulation. I also struggled with low progesterone middle of last year until i started taking progesterone to get my period and then letrozole to ovulate.

Is there any advice or any way i can fix this? I’ve been ready and trying to conceive since i lost the baby.

Any advice helps
