Morning sickness

Katie • Hubby and I are expecting our first child together in March!
I am 8 weeks today. I have had nausea off and on for the last few weeks, but starting Friday, I have been getting the feeling of vomiting. I hate throwing up and I have been focusing on keeping everything down, even though I know I will throw up if I allow it. Don't know how much longer I can keep this up. Anyone else do this, or do you just throw up? Ugh I hate the feeling!
