What is going on?!

6 DPO

Had temp change, juststarted temping 6 days ago now.

Keep getting positive then negative lh tests the cycle just repeats.

I got off birth control in July.

I have an appointment with my doctor 10/18.

She told me to do opk’s every day until then.

Just soooo frustrated because I do not know what is going on and I do not think I’m ovulating.

Anyone else go through this???
