Why can’t I get pregnant

Ga

Super disappointed because I really thought this was it. It’s 12dpo and still negative. I don’t even feel af but I’m sure she’s coming now. It’s month 4 and after a chemical month 1 we can’t get pregnant again. We’re both feeling like maybe I can never get pregnant again and I’m crushed. Anything work for you to get pregnant? Im have a regular cycle, I ovulate around the same time, I eat pretty good, pretty active… I’m almost 26 and he’s 31… not sure what could be the problem.
