Af due 4-9 buddy?

Hello, I am Angie. We have been ttc 5 years. After some long struggles we are fully all in trying again. I have just started using the fertility monitor this past cycle.... Seems as tho I have not been ovulating when I thought I was for all those years! Fingers crossed... Hopefully this past cycle with the help of the monitor that showed me 2 peak days on day 20 and 21 we will get lucky! Although is that late to ovulate? I am thinking that's why all these years before nothing worked because we had sex on the wrong days!! Well, fingers crossed!
