wheni was pregnant with my twins, i had a couple of episodes where i would have horrible contractions and i would go into the doctor and they woudl monitor me. while they did that, they gave me tons of water. i would suggest that this timearound, drink lots of water to begin with and it might not be as bad. i am 36 weeks pregnant right now and have had one episode of contractions-real ones, not braxton hicks- and all i did was recline and drink 40 oz of water. after about 30 minuted they stopped and everything has been fine since then, my doctor tells me, because i drink so much water. and if it really bothers you, talk to your doctor about it to try and come up with a plan. i find that when something worried me like you are woried about this, it always seems easier to get through with a plan laid out. plus you might not have any preterm labor this time around because every pregnancy is different. good luck andi hope everything works out!!!
