Sounds like you are either having aversions or your body doesn't want to let go of the MS. That was my entire 1st trimester with both pregnancies (DD and now)!
Is your tummy empty? I found that when I hadn't eaten, (because i felt nauseous), it made it so much worse! I had to force food down or if couldn't, a glass of milk. It made me in general feel a bit better, and the nausea subsided a little.
That's how my first trimester was. Knock on wood I'm still in the clear from vomiting. Not one time did I throw up. Which I'm very thankful for. The nausea subsided a few weeks ago. I would drink water and eat a few saltines to help mine.
Re: i have so much nausea, no throwing up, just feel sick from time to time??
Hope it passes xx
