Sometimes I want to give up

My husband and I are both 24 and have been together since 2006 but didn't get married until 2013. We have been TTC for over a year and I'm losing hope. My physician said if nothing happens soon, he's going to start tests which I really don't want. I started using Glow and it's start days are pretty on sync with my cycle. I just don't know when I ovulate. I have to take tests for that. But it says my period should start today and I don't even have symptoms of it. Hoping and praying. Because mentally I've had enough......
