Hello, first time posting here so sorry if this isn't the correct place to submit this post.
I'm coming on for 10 weeks pregnant, and had morning sickness since week 4. Morning sickness from the get-go has been vomiting and vomiting multiple times a day. (First time pregnancy).
I've tried a bunch of stuff that's meant to curb the sickness (eg. ginger, mint, sour sweets, broth) but nothing seems to work. The only thing that reduced the vomiting / could push it off a couple hours was drinking flat Coke and Lucozade. I'm not a regular drinker of fizzy pop, I drink water usually but I kept throwing up water... But now, the flat Coke and Lucozade is no longer working and whenever I drink it I just bring it up within a short amount of time.
I only am eating dry foods like crackers / toast / baked potatoes because that's the only thing I can stomach, but even then there's no guarantee it'll stay down. It seems that my body gets "tired" of particular foods after a while so rejects them, for example I was eating digestive biscuits, very mild cheese, soups, etc., but after a couple weeks I couldn't keep them down at all so stopped eating them. I'm quite anxious about what to do when my body decides it doesn't want crackers or toast or potato anymore, then I'm not sure what foods to move to. 
Any help or anything like that would be great. I know it often for women goes away by the 12th / 13th week, but that's only like 60% of the time or something. I really need something because I can't even do light exercise at the minute without needing to vomit.
