Any recommendations for fertility?

Hi all so I'm trying to get pregnant after a miscarriage. It's been 6 months now . I did my basic work up just the blood work and ultrasound at a fertility clinic everything was ok on that . I just need to do a saline sonogram. But my question is . Is there any recommendations to help boost fertility I am 35 . And same for my husband he hasn't done a work up yet but will . Is coq10 supplement good for male and female?
