tonight I go and have a nice dinner with my dad. and past few days not feeling well. everything is making me feel sick

order what seemed like an awesome shrimp dinner and only lasted for not even a minute. and almost threw up all over that restraunt! lol thank god I held it back! was super exited about not feeling sick with this pregnancy and then it hits full force. just had to vent! any suggestions what to eat so my baby get the nutrition until I get over being sick???
