So I've had 17 Braxton hicks within an hour and a half. Don't know if I should go in since they don't hurt. I'm already dilated to a 2.5 and my cervix are really soft according to my doctor and he said he doesn't think I'll make it to 38 weeks. Any suggestions? I don't want to go in and they just send me home especially if they don't hurt.
