NO!!! You want that baby too cook as long as you can. I saw high a high risk dr. most of my pregnancy. He said even though you are nearing the end, even having a baby 3- 4 weeks early, puts the baby at higher risks for all kinds of illnesses as an infant. Babies born earlier, are not typically as healthy of infants. They also tend to have colic. They have bigger chances of learning and behavior problems down the road. (This is experts and science talking, not me!)
I also started having preterm labor issues, but around week 24. I had Hyperemesis gravidarum from the beginning to the end of pregnancy. My doctor wanted that baby to be in there for as long as we would manage it. She had me rest as much as possible and made me drink a gallon of water a day. (To avoid any amount of dehydration, which can cause early labor.)
For the record, I was dilated at 2 for 4 weeks. In fact, I never even went into labor and had a c-section 3 days before my due date. (Other complications made a c-section necessary.) Don't start labor. Every day that baby is in there, benefits the health of the baby. Full term is not at 35 weeks 5 days, for a reason. Just because, they won't intervene, does not mean that it's the best time for a baby to be born. After 36 weeks, it's easier to birth a baby then to keep it inside. That does NOT mean, that you want to kick start it. Let things happen on their own.
