Okay mummies in serious need of some opinions please ! Yesterday I went out for dinner and about 5:30ish I started getting horrible painful stomach cramping (it just came out of nowhere!) lasted on&off; for about an hour & a half , then the pain moved to my back and my back was in agony!! Then the pain left so I decided to go to bed about 11pm then just as I was getting ready for bed the pain was back again I was in agony I actually thought I was in labour was doing my breathing exercises & everything , managed to get to sleep but iv woke this morning with still some cramping not intense like yesterday but still uncomfortable , not to mention the top of my belly goes hard and so does the middle ! Not the bottom though! :/ any ideas ?! Please help :(
