TTC After Tubal Reversal

Hi Everyone. I'm just looking for advice or anyone else's experience. I had a tubal reversal at age 37. It's been 7 months. My OB/GYN did not seem concerned with my age and the time that has passed since the reversal. I'm bothered by it. Can anyone offer any insight on if I should be worried?? BTW, I had a chemical in April.
