Which OPK to choose

Lola
So damn tired of these BFNs and AF showing every month. I'm so depressed and frustrated. I just want my baby already!! I'm on prenatals and we are using preseed. I'm starting to think Glow isn't accurate with my ovulation dates so I want to start testing to see when I actually ovulate. Which do you recommend based off of personal experience. I don't want to waste my time with the cheap strips that I can never understand. I need a digital result so I know for sure what's going on.
