Help!

Tess • 19. I💙my son! I wouldn't have it any other way❤️ engaged to my wonderful fiancé!
So I went in to my appointment today around 2:30 pm. I was checked to see if I was dilated, I ended up being 3cm and 70% effaced. She told me I would spot afterwards but I didn't, it's not 1:30am and now I'm spotting and losing more of my mucus plug. 
Normal? Or should I be worried? 
My due date is this Saturday!
