Testing

My husband and I have been TTC for exactly a year now. No luck whatsoever. I've actually been using a fertile day tracker app outside of glow until I found out about it in November. The only thing that's notable is I had a false positive in May. We were both excited because it was just days before his birthday😔😔 so my question is... Both of us have decided it's time for testing to make sure everything is okay and healthy. Can someone help me out of what this consists of so we know what to expect at the doc's office! He is very shy! Thanks in advance. Ps.. We are trying for baby number 1
