Spotting

Jen
I just went to the bathroom and I felt a small gush of fluid. When I wiped it watery and pink. I am 13 weeks 4 days. I stopped taking progesterone Wednesday. Not sure what to do. Of course this happens on a Saturday! 
I had an ultrasound just over a week ago because the doctor couldn't hear the heart beat with a Doppler. The heart was beating and the baby looked like it should for a 12 week ultrasound. I have an appointment with my OB Wednesday. Freaking out!
