(Im sorry for grammar mistakes)

A little back story, so my husband and I have been married for 2 years now , happy and testing ! Due to medical reasons ,”I.e” having a period for 6 months straight. This Past April 2018 I had a medical procedure done to clean my uterus out and they found a non cancerous fibroid. Since the surgery my period has come like clockwork every month. At the Beginning of July me and my husband was TTC during my peak days . My period usually comes on the 23-24 of the month. I’ve taken a test and still Neg. should I go back and see my doc or just wait it out a little longer. Or would getting a blood test be more accurate? I need advice !
