Ovulation test

first time mom

So I’ve been taking ovulation test the last 6 days. See picture below. First two were low, The last four days I’ve been getting a blinking smiley face- means high fertility-ovulation soon. I’ve never gotten it four days in a row without a peak yet. (Peak means near ovulation).

Has anyone else experience this or have an idea of what’s going on.

I have a doctors appointment Thursday to just chat with the doctor about trying to get pregnant so long.
