Help please!

Ha

I just started charting with ovulation tests.

Does this drop mean AF is about to come?

I stopped taking BC in May and had only 3 days of very light period 25-27th, no period in June and so far nothing in July either. The pink box is just predicted because I’m currently on day 57 of cycle and could only input typical cycle length and couldn’t leave it blank. It’s set on 30days. No idea what my cycle days are yet.
