No period 3 months !?!

This will be my 3rd month no period.

I have taken pregnancy test and all have been negative.

I have very tender and painful breast they look a little bigger too.

I have a appointment on November 4th. ( couldn’t get one sooner unless i change doctors but im not comfortable w male doctors )

I have no spotting. I also have really bad and painful acne ☹️

I’m guessing a hormone imbalance?
