Help please! I would love some advice

Hey guys, so I've been taking prenatal vitamins, I'm in the military so I workout daily and eat right and maintain a pretty Good weight, my fiancé and I have been TTC this is the 3rd month. I track my ovulation and fertile window etc so my question is, is there anything else I can do or take to become more fertile? We are both in our 20s too surprisingly it's not as easy as I thought it would be to conceive.
