Please help me! I’m new to this and confused

Hey all,

Right I’m pretty confused and need everyone’s advice as I am not too sure what is happening.

I had my period this month, and then glow said when I would be fertile- (see below)

I started taking the clearblue digital tests and I had flashing smiley a week before glow said I would. Anyway, I think I ovulated- see below.

Yesterday, I took a digital and it said low. Today, I get a flashing smiley.

What could this mean? I’m not sure what to do as I don’t want to miss anything.
