Early ovulation spotting on CD7?

So I’m pretty sure I had ovulation spotting yesterday. It was super light pink and very little of it. It went away after peeing a few times. Disappeared for a few hours and then last night happened again when I went pee before bed and that was it. I woke up this morning and haven’t had anything since. The spotting was so very little but I noticed when I wiped.

I’m not using OPKs this month because I’ve just been going through too much money these past few months.

My AF started on the 15th and was gone by the 18th. It seemed like a normal but short period.

Then I had light pink spotting on CD7. I BD this morning just to make sure. My temp was 97.5 this morning.

Has anyone ovulated this early before and got a BFP that month? I’ve never had this spotting before. I’ve read mixed reviews about early ovulation.

Last month I didn’t even ovulate.
