Bbt and vvvfl and also spotting


I'm so confused! Last month I had a chemical and it was devastating.

Yesterday I had some color in my cm so I marked it as spotting and thought af would show up today.

I woke up this morning and my bbt increased and no af... just slight color in my cm.

Took two realllllly cheap tests and see this. I even did one hpt with water just to make sure they aren't fake lines.

Is this real? Should I be concerned about the super light spotting?
