Frustration. Maybe TMI in this post, but i am becoming very discouraged

Heres whats going on, i need advice, please.

Me and my love grew up together, dated in our 20s, then parted ways. While we parted, we both found what we thought was "the one" for both of us. We were wrong. Mine, committed suicide due ti depression, last april. His, just up and decided she no longer wanted to be married to this wonderful man, after they were only married for one year (shes a fool).

So, we re connected, last year.

Ever since we got together this time, we both knew it was forever. We have never used condoms, and he does get off in me. We want children. He turned 33 in may, my 33rd is next week. We want more then one, so know we need to try now. We have been unsuccessful. We both smoke cigarettes, but neither take daily prescriptions, and neither do any sort of drugs. He drinks almost daily, but not much... like a beer or two, but never gets drunk or anything. I do not drink at all, ever. I am 5'7" and 180lbs, so im definitely not thin, but also not huge. He is literally target weight at 190 and 6'2". His job is extremely physically demanding, and he is exausted daily. We dont have sex daily, hell, sometimes... not even weekly. Most of the time, his body is just so worn out, he cant get off. So lets say, he gets off in me about 4 times a month, all scattered dates. The rest, theres no ending for him, just me. I have tried diet change, pre natal vitamins, and alot of old wives tales... my older brother has 2 kids, when he was 32 & 34. My younget sister had hers in her 20s. My mom had us in her teens, then a few miscarriages. All of my aunt's on both sides had issues conceiving, but my doctor ruled out the conditions they had, already in me...

His family has no known issues with pregnancy, but all the men, him included, have high blood pressure.

Can someone give some tips as to how to make myself more fertile? Doctors tell me all of my testing is perfect, and that my body has no medical explanation as to why we havent conceived after more then a year of trying. I know smoking doesnt help... but we both have cut back, to less then a pack a day (about half), but that didnt make an impact. We do have sex every month during my "fertile" window, according to glow. I am almost ready to try anything. Suggestions, please.
