Ovulation Kit

Tested this morning with an ovulation kit and the test looked like it went cloudy so I assumed it was a dud test but I waited anyways. After about 10mins it went negative but still had a decent line.

Tested about 5 hours later and I think it was positive but <a href="https://play.google.com/store/apps/details?id=com.glow.android">glow app</a> said negative.

Tested again tonight to check and now it’s a light colour and defs negative again.

Did I miss the surge today ?

Or is it likely the one from tonight might not be accurate?

Any help appreciated 😊
