12 weeks pregnant

Currently 12 weeks pregnant ...pregnancy has been going smooth for me so far no morning sickness of nun besides having a lil gas every now and then I’ve been good. But today i threw up for the very first time now I’m sittin here tryna figure out what I’m going to eat later because i don’t wanna throw up again ...but my stomach isn’t hurting or anything i actually feel fine I’m just kinda scared for what reason idk so what are some things you guys eat after you throw up. I’m debating on should i eat something light or don’t be afraid and just eat whatever i want. This my first pregnancy btw
