I'm in labor. The blockage cleared when I called my doctor. She told me to call an ambulance. I ignored her and left. Now I'm here with contractions, but there's nothing, high blood pressure 150/90, they're constantly squeezing my cervix because it's ready for delivery. I'm exhausted, and what's worse is that there are no contractions at all. Has anyone experienced this? Share your advice.
