Hello people who know a lot more than I do 
I have been feeling dizzy if I lie on my back but I am only 11 weeks. I didnt think this was supposed to start until well into the second trimester. Had nausea off and on but it stopped at 10 weeks and havent had any since so I dont think this is related
But feeling dizzy while on my back, this early. Is this normal? Already have a bit of a bump, which surprises me too since this is my first. Keep telling myself its bloat.
