Why is my body so weird

I don't understand this.

My last period started oct 1st. Lasted it's usual time, 4 hell days, no big deal.

It is now nov 16th. I have yet to have another period.

I've done the logical thing, I took a pregnancy test which came back negative.

I do have a history of ovarian cysts which it obviously could be.

WHYYYYY IS THIS HAPPENING!!!!

I've never wanted a period to come, let alone as bad as this!
