Fertility question

Tiffany

I've been off the pill since January. I've been trying to conceive but it's like everyone around me is getting pregnant.. I'm 31 and my partner is 44.. Should i make an appointment to get checked and him as well.. I'm starting to worry his past actions may have made it impossible at this point or there is something wrong with my parts.. I do have 2 children from a previous relationship soon to be 13 and a I year old and he has 1 child well adult now. Any tips I can do to help like vitamins or just get a check up
