A little advice please!

I’m kind of confused. I know both lines have to be as dark as each other or the line darker than the control line.. I thought today (day 14) would be darker than yesterday but it seems like it’s lighter... I’m on clomid this month so I thought I’d ovulate around a normal cycle. Am I just seeing a lighter line or what? I’m still new at these strips. Please tell me your opinions/advice. I’ve also been having mild cramps/sharp pains in my lower abdomen and my boobs feel heavy today. Maybe it’s getting close?
