Irregular cycles

No signs of PCOS but I do currently have pretty irregular cycles. Any tips for helping to regulate? I’m TTC so birth control is not an option😩. Help

Last month I tracked my cycle which was 43 days. I ovulated on CD 30. (Confirmed with opk and BBT) then I got my period exactly two weeks after ovulation.

This cycle I’m on CD 31 and have not had a positive opk or a bbt spike.
