31 weeks pregnant

Becky

need some advice please ladies, am 31+5 weeks and last night I was getting really bad pressure right down below which I could hardly walk and feel like I need to wee all the time but nothing comes out. Then baby starts moving so much but she is like that anyway, woke up this morning and the pain in the bottom of my back is so hurting, I don't know what to do? advice please girls?
