I’m so confused. Help please!

Chelsea

I had this CM on the 5th of August.

And this CM today August 13th.

I’m just so confused because can I ovulate twice in one cycle. I should be welcoming aunt flow on the 18th. Am I wrong about those pics being ovulation CM? Someone help me out here please. I’ve taken two pregnancy test just because i had sex every other day on both of those times I had CM mucus like that.
