Ovulation frustration

I know some women don't get obvious line progression and just get their blazing positive but I'm getting a little discouraged. With my son my lines gradually got darker and now I don't see a change and my predicted ovulation is In 2 days.

I'm getting a little discouraged. The only symptoms I have are swollen boobs and an increased (ish) sex drive. With my son I had a dull ache in the lower left of my back. I didn't have noticable EWCM but right now I don't have many symptoms indicating possible ovulation. I want to try for baby #2 but last time I got so caught up and was let down every time and I'm worried.

I need words of encouragement
