Found out 10 days ago that I am expecting my 3rd child. Everything has been fine until last night when I started getting pain in my lower left pelvis. Woke in the night, was so dizzy I couldn't stand up but the pain had gone. Since about lunch time today it's come back and seems to be getting worse. Every time I bend down or sit in a funny position the burning pain goes through to my back. Never had this with my first two, I was expecting stretching pains etc but because it's one sided I'm starting to worry a bit....
