Period due in 9 days.

And I've had a lot of cm today firstly it was creamy but watery and I just went to the restroom and its the egg white really stretchy stuff... I'm sure I've already ovulated last week So I was just curious.. I've never had the stretchy cm except when I'm near ovulation.. could I be pregnant? Or is my body just being weird? I also went to do a cm check earlier today and the walls of my vagina were swollen? I guess is the best description??? Like increased blood flow. Is this because my period is coming or could I be pregnant? I've never noticed this happening before so I was just curious. Thanks!
