I fell downstairs at work at lunchtime today - I'm 16 weeks. Rationally I think everything is probably fine: I'm not bleeding or cramping (though of course I'm really noticing every little twinge at the moment). Judging from the location of the bruises I landed mainly on my left knee and hip. I rang the hospital and they said make an appointment with my GP - can't get a GP appointment till Thursday, which seems pointless as I'm due a scan on Friday anyway. Come and tell me you've done the same thing and everything was fine!
