Had IUD for 15 years

I had my IUD for 15 years and got it removed in April. I have one child she’s 15. My husband and I recently started trying for a baby (3 months ago). My body is way out of whack have periods twice a month and I think I had a miscarriage the first month of trying (April). What can I do to get my body aligned to prepare for a baby. I’m 38 will be 39 in September.

I do a lot of labor intense type work… I work in a warehouse, lift boxes, stack boxes, unload trucks, pull and push pallet jacks, also I am a Amazon delivery driver :)….
