ugh....I think I've been having Braxton Hicks....but I'm not sure. and although this is #4 I don't remember what's normal and what's not. I'm going to tell you all what's going on and maybe you could help me figure out what to do...

-tightening lower ab area (between my hips) and when I press on it, it feels like a ball in there. pretty sure it's contractions.

-Constant dull pain in my lower back and into my legs.

-pressure in my vagina when standing/walking

-slight discharge (white in color) no smell tho

that's all I can think of going on right now. thanks ahead of time ladies, appreciate your help. I just wanted to get some opinons on what to do before I freaked out or went to the hospital.
