Looking for some moral support. Ive been chatting Bg for 2 months as I've had irregular periods ranging between 24 and 29 days over the past 6 months.

My bbt shows clear ovulation and progesterone rise and I've had all my blood tests and pelvic scams showing all clear on anything underlying. However I'm ovulating around day 20 and then today 9dpo here is my period. I'm sure this is why I'm not getting pregnant and now I'm so worried the more things you read the more worried I get. Ive got an apt with my gp first thing tomorrow which is good but she isn't a fertility expert. What should I be doing? Has anyone been through the same and got pregnant?
