Ovulation Question

Ok, this might make me sound crazy but I have a question. We have been trying to concive for over about a year and a half now. I met with a fertility specialist last week and she wanted to start by seeing if I even ovluate. So according to the app starting last Sunday I was supposed to be ovulating

1. Is it possible to ovluate a week later than Glow states as I feel I do

2. When I take my ov. test it started with only the control line and has moved to both lines the last 3 days, does this possible mean I am getting closer to ovluation?

- I know the test line has to be darker than control line

Am I correct in reading this that I am NOT yet ovulating?

Thank you in advance for any insight!!!
