Clearblue digital and glow - confusing!

Hello,

So yesterday I took a Clearblue digital OT and I got my peak. Smiley face

I entered the data into flow and it predicted ovulation as today.

Today I took another test and it was negative and again I put the info into glow and it has now updated to say I’m one day past ovulation.

What I don’t get is that when you get a smiley face you are supposed to ovulate within the next 12-48 so how could I be once day past ovulation already?

I know it’s just a prediction but I’m so confused!

I’m scared I’ve missed my chance this month as ovulation came very early. Lucky I started testing or I would have missed it.

Feel like we did not get enough BD in before ovulation :(
