HELP 37 TTC for 5 months when to see Doc?

Lo

Been TTC for 5 months 37 yrs old and hubby 28. ( yes I know he’s young) anyway I went to the fertility Dr. before TTC and got the basic ultrasound and they tested my AMH and it was a 1. The Doc said that was good for my age and my ovaries looked good. Also no medical issues. My question is how much longer should I wait to see the doc. again to get my tubes checked for blockage and such? Also the boys are in good shape had those tested also.
