Okay... Following up from earlier!

The bottom one is from yesterday, top one today.
I have never taken ovulation tests before, because really I've never needed to know when I was ovulating! After having no luck TTC for almost 2 months now, I bought this pack and started using these ( First Response ).

Just to restate, my last period was December 21, 2015. I got off my pill before that period, but had been on the pill for about 9 months prior. We had sex during what we were almost sure was my fertile window! Many different times, but not too much. 😊
After, I took tests when I thought I was pregnant, but hadn't missed my period yet. Negative tests, so we kept trying, just in case I was off with my fertile window predication!
I missed my projected period on the 18th. But as you guys saw, I took a test between then and now, and it was also negative.
Like I said, maybe my pill really affected me!
I'm on day 42 of my cycle.

Can you guys help me? Does the line becoming more faint each day mean I am approaching ovulation?
Or, leaving it? (Would confuse me if I have ovulated!)

Thanks girls. 😊💕
