Tired of ttc... Any tips? What have you used?

It's been a year of ttc for my husband and myself with 1 miscarriage and nothing since. I want to go to see a doctor but because of my job schedule I can't really, at least not for a few more months.

Every month with AF showing up gets worse and worse, and I'm not sure how much more my mental health can take. I'm considering taking a break or giving up altogether, but when I mentioned it to my husband he seemed really disappointed...so I figure I'll give it a month or so more.

We chart bbt, track cm, use opks, we use preseed... and have for a year with the aforementioned results. Does anyone have any other tips, anything they used to help conceive, certain vitamins or anything?
