I agree to call the doctor. I have a friend whose baby had caused a small hole in the placenta. She was slowly leaking amniotic fluid & didn't even realize. When she went back for her next appointment, her weight had dropped so much that they immediately did an ultrasound & discovered her lack of amniotic fluid. They ended up sending her to the hospital and inducing her right away. Her son is a very healthy 6 year old now, so all was okay, but I certainly would not delay lwtting your doctor know.
You should call your doctor
