I hate this..

Brook • I`m 26 years old and I have a beautiful daughter named Daisy! 💛 my husband and I went through hell to get pregnant with her and now we are hoping for a second 🤞🏼
I have this app and another one called ovia..they both are telling me two different things on my most fertile days..I'm not sure which one to go by..plus I don't even know exactly when I ovulate because my periods are very irregular..anyone have any advice on how I can figure it out or which app I should follow?
