Been ttc for the last 10 months...

And AF shows up today.... I don’t know what to do anymore. We’ve tried sex every day of my fertile window, we’ve tried sex every other day of my fertile window. I’ve cut soda, all alcohol. My periods before my first ( had her a year ago) were normal, then had her and they were off. I was going two months with no period. The last 3 months they’ve been back to normal, I’ve been following the app for my fertile window and at this point I’m at a loss... I think hubby needs to get checked:/
