Ovulation Test, important queations/curiosity please respond

Has anyone ever gotten an early peak on the clear blue advanced digital? Last month it popped up the day after my period. I just tested and it popped up about 2 days before my fertile week starts! It's baby making time! However I'm wondering if this is normal for it to pop up early plus I have a Dr appointment tomorrow afternoon for my annual and to discuss any help they might have.

A little history on myself I had a miscarriage last Dec, I'm wondering if that changed and that's why Dr s say to wait before ttc again?!

Oh and this month I have both the mucinex and the preseed to help!
