I'm 10 weeks pregnant and although I have a lot of nausea I've only thrown up a handful of times. However I seem to throw up really violently, it's like my insides are coming up, and every time it happens I feel really intense pressure in my head, like it is being squeezed. I have so many burst blood vessels around my eyes from the force of it. Is it normal?! It's my second pregnancy - with my first I had only very mild nausea and never actually vomited.
