what the hell is going on?

Tionna • Married 💍 IVF boy/girl twins 💕💙 lost baby girl in 2nd trimester 👼🏽
Hey ladies,
So I use 3 apps. Glow, Clue & FF. I have been using Clue the longest so it knows my pattern the most. All of the apps say that I ovulated on the 18th or 20th, but I didn't ovulate until today, the 23rd (I took the CB advanced OPK). Now hubby and I have been trying for 7 months but I have been solely using the apps. I am kind of upset because the app is 3-5 days off which is a huge time difference. I could have been missing my egg every time smh. This is our second month using OPKs so I guess I've only been accurately trying for 2 months. I'm so discouraged and my husband keeps telling me he wants a baby. I just wanna scream "IM TRYING". About to go into the TWW and I hope I don't drive myself crazy! 😒😞
