AF came today

I’m a SMBC and I’ve been TTC for over a year. I’ve been timing my cycles, checking CM and position, taking OPKs, taking supplements, and tracking bbt. This last cycle everything was timed PERFECTLY, and I for sure thought it would work. But AF came today and I’m more devastated now than I ever have been. I’ve wanted another baby for so long, but now I’m considering giving up. I have 2 daughters already and I share custody with their dad. I really just want a baby, one that I raise myself. I have people telling me to keep trying, and others telling me to just be grateful I already have 2 daughters. Am I wrong for wanting another baby? Should I just give up on my dream?
