confused

Jodee

I am applying progesterone cream for 12 days.. today is day 9. yesterday I had pink blood on the toilet paper when I went to the restroom. I have not had a period in 7 months due to pcos and low progesterone. my temps were stable until this mornings. I'm so confused why I would drop like this. i take temp at same time each day. nothing changes in my schedule. anyone know what this could mean?
