Am I ovulating or already ovulated possibly??

So, I took a ovulation strip yesterday & it was positive or very very close to positive. I took one last night thinking it would be a slight bit darker & it was lighter. I took one this morning & it was even lighter.

This is the one from around 2 yesterday.

These are all three together starting with the one I took at 2 yesterday. & the bottom is the one I just took this morning..

I am having my ovulation symptoms or soon I think I am. My nipples are sensitive/sore & my stomach has been cramping a little & I just overall feel groggy.
