this is my second baby, but with my daughter i never had back labor. i felt all my contractions and labor pain around my belly button. but ive had contractions for 50 seconds every 20 minutes which isn't too worrying right now, but my back has been constantly hurting for the past three hours which is about as long as these contractions have been happening.

i think the contractions could just be BH, but I've been laying on the left, ate and drank a bunch of water in the last hour and nothings changed. called my ob she said only go in if my contractions drop to every 5 minutes.

im just curious what back labor feels like so i can tell if i should just go. i went into preterm labor at 36 with my first (they stopped it and i carried to 39) but im 35 today so i dont wanna wait too long if i am in preterm because I'd rather them be able to stop it so he can bake a lil longer.
