LONG POST!

Hi Ladies. Currently 10DPO. Been having stark negatives . AF due in 4 days . Before i started letrozole this cycle, i had labs done that showed my prolactin was a little high. My OB told me that could be a reason im not getting my menses.

Anyways I confirmed ovulation 6dpo it was a 6.7 (anything over 3 is considered successful ovulation with my clinic). But sincr my progesterone wasnt as high as a 10 or above, will i still get my period then it im not pregnant? Thank you for any insight!!
