Can glow be wrong??

Question

I just wanted to know with our bodies changing along with hormones sometimes....can glow be wrong about our ovulation/ fertile days

Answer

Yes. Any app is just providing an educated guess.

Answer

It is just an estimation based on the information that you provide. If you want to know for sure buy some OPKs and test so you know exactly when it's happening. I ordered 100 on Amazon for like $15.

Answer

Yes of course. This is just an aproximation for you to have an idea

Answer

Glow says I was fertile from December 1-7 but all other fertility calculators say 9-15.....
