Any of you use the clearblue advance digital??

I used it in October and I got the flashing smiley for 3 or 4 days before I got the steady smiley.. I fell pregnant that cycle but I unfortunately miscarried on week 12..

I used it again last month and got flashing smiley for 3 days before I got steady smiley..

Then this month I used it again.. finally got flashing smiley yesterday am, (expected to get a flashing smiley 2 days ago) I tested again pm before I went to bed and got steady smiley... isn’t it weird to get the first flashing and a steady on the same day????
