Bad ovaries....

My SO and I talk about wanting kids but we aren’t in the greatest spot in life, but we also aren’t getting any younger and I have issues with my periods as is.. He talks about how if I did get pregnant we’d have to figure out how to go about when he got home from work (he works at a mine around a lot of acids and just bad air) like how he’d be around me and doesn’t want me to be inhaling all of that bad stuff cause he doesn’t want anything to happen to baby.. but also we just recently found out he has very low sperm count.. I’m at a loss and don’t know what to do or try.. yeah we may not have everything we want but we manage he gets paid weekly and has option to work overtime as well and sometimes has to work late anyways and he makes decent money.. my question is what can we try at home or some supplements or something to try here at home without have to go to the doctor for it.. any ideas?
