Can someone please help me with BBT charting process.

This is my first cycle that I’m tracking after we decided to TTC.

So I took a ovulation advance test this morning (11th) but the result was low although the <a href="https://play.google.com/store/apps/details?id=com.glow.android">Glow app</a> did say I had 11% chance of getting pregnant.

My Question is when is the best time to take the Clearblue Ovulation test ? For better chance of conceiving.. How many days to ovulation according to the app should I take it? Should I take the test twice a day ?

It’s just all confusing so if anyone can help please.

Thank you in advance
