why does it hurt to sleep on my left side? like the left side of the stomach feels hard when I am sleeping and i can't lay on it anymore I have to sleep on my right ( I can only fall asleep on my stomach but either facing left or right with one leg bent up towards my chest ) ... I really hope this blood test tells me if I'm pregnant or not. I would love to be but if I'm not then there's something seriously wrong lol.
