My husband and I have been trying to conceive for about half a year now. I've been using this app and ovulation tests and no luck yet. I saw my obgyn a couple months ago and asked how long we should try for before seeing her again if we don't get pregnant. She said try a couple more months with ovulation test and keep trying then come back and we will look into it. I'm going to give it a couple more months but has anyone else done fertility tests before? How does it work? Is it expensive like everyone says?
