For the last few weeks - I am 24 weeks... I have been having mild pain in my left leg and groin area. It aches and can feel it wen walking but it has not stopped me doing anything. I didn't know if it was spd with being just one side so pretty much ignored it tried to crack on...
It's got steadily worse but again I have managed to do everything I need to etc.
Been to work today - it was alright, just the usual pain but when I walked in my front door it's just hit me like a tonne of bricks. I am in agony all around my left hip and my groin, my leg is throbbing and it actually feels like someone has stabbed me in the vajay! 
It's so sudden and painful I got upstairs and am lying on my bed ATM while DH sorts tea etc. this is my first pregnancy and I don't I ow what the hell this is or what to do!
And ideas! I'm stuck!!
