Stopping with Progesterone @ 11 weeks

Macki
Hi
I am 11 weeks tomorrow (due date 1/2/16). Ive had 2MC recently and Ive been on Progesterone (oral x1 daily) since week 5. I am told to stop completely with it @ 11 weeks but pretty nervous about it! I know the placenta take over @ around 10weeks and I have to trust my doctor but it would be nice to hear your thoughts and experiences.
