Irregular Cycle - TTC

12/21-12/24

1/21-1/24

Nothing for February and nothing in March yet. My husband and I are TTC and stopped using protection since the end of November. We tried to use ovulation tests in January and testing around the times that I usually ovulate and also based on what my tracking apps say, but they were not showing I was ovulating. I have an appointment with my doctor on the 15th but I’m just worried that I may not be ovulating any. I have also been experiencing more discharge, clear, sometimes white, in the last few weeks
