Contraction City: Prayers Needed

I fear the contractions have already begun. I experienced pre-term labor with Griffin starting at 28 weeks. Luckily he stayed in the oven until full term at 39 weeks. I believe it was all the prayers that kept him safe and healthy. I ask for your prayers again. I have not contacted Dr. B's office yet because the contractions are not in regular intervals (like every 5 or 7 minutes) and because I'm stubborn and don't want a trip to the hospital. But, I have noticed a marked difference since Sunday afternoon. Over the course of this week I've had days with few contractions followed by a day of continuous contractions. Today is one of those continuous contractions days. At my appointment and ultrasound on Friday, I was experiencing very few contractions. But they have definitely picked up every day since Sunday. If things continue as they are through the night and a large part of tomorrow, I will be calling Dr. B for instructions on next steps. Thanks for your prayers.
