Morning sickness and nutrition

Hey everyone, I'm 7w5d and have had nausea almost constantly since 5w5d. I puke once a day at least, and my food aversions are literally almost everything. The only things I can stomach are saltines, cheese pizza (?!) , Cheerios, water with gatorade, jello, applesauce, and minestrone soup. That's it. I take my prenatal vitamin and B6 but I'm worried because I literally can't stomach vegetables right now:( I've got to force myself but it comes back up sometimes :-( has anyone else been in this situation? I'm worried my baby isn't getting what it needs :-(
