Questions and confusions!

So I'm very confused. I really have no idea when I will be ovulating or if I already have ovulated. I miscarried in August and still haven't had a period. I decided to take a opk like 4 days ago, and most of them had a vvvvvfl, that got a tiny bit darker. Nothing too serious. Does the test normally have vvvfl? Or is it just a flaw. The top one has the most prominent faint line. Do you think I could be about to ovulate?
