Question

I have 5 apps for TTC (obsessed I know)

The dates I am due on for AF vary from 3rd June, 6th June, 7th June and 10th June....

What one would you listen to?

Answer

Glow is always a week off ovia is within 2_3 days. I keep glow for community lol

Answer

Glow was exact for me the first month. I think it just depends on your body. But I know that glow will change its predictions based off your logs.
