I am 4 1/2 weeks pregnant! Anxious and worried just hoping evey thing turns out great and healthy! Yesterday at work I had terrible pain in bottem middle of back when standing and moving in certain ways! Was terrified but when to doctors and she said it was nothing to worry about just sciatica and to rest and if it was miss carriage the pain would be constant and I would find no relief in any position!also would have cramps and bleeding! Today my back feels. Little better but still hard to walk around as it is a over whelming pressure in the middle! Will this be harming my baby? Am terrified any one else had same thing or know any info x
