Trying for 6 months...

My husband and I have been trying for 6 months to get pregnant and I feel like it's never going to happen. This month I keep hoping that it's different because with this app I was told my period should start the 20th and I still haven't started... But I know my period didn't start last month till around the 25th.. I took a test a couple of days ago and it was neg.😕
