9 weeks pregnant...

Idk what to do... I can't think of any foods without feeling nauseous. I barely eat but I'm so hungry (I do force myself to eat though) and I get these really bad headaches. This pregnancy is totally different from my first. I feel so miserable but some days are better than others. ☹️
Any tips for the nausea? I don't throw up (only happened twice) but I get constant waves of nausea like every single day ..
