I've been having pains since 8:30pm, just on and off and like medium bad period pain, they are not at all regular and ease when I'm up and about and are worst when I'm lying down but I also feel some pressure....TMI alert.....but it feels like I need to do a big poo and when I go to the toilet nothing comes......except maybe some wind.......sorry, embarrassed face!!.........could it be labour or could I be way off??? BTW I'll be 37 weeks on Tuesday.
