Constantly sick!

So I’m 16 weeks and I’m still nauseous all the time. My sense of smell is often the culprit because now even a whiff of foods I used to like make me gag. I feel like I’m being ridiculous by how often I gag and puke. I tried ginger, b6, nausea relief candy and I’m still getting sick. Idk what to do anymore. It’s a chore just to get enough water each day without it coming back up. I’m always hungry because everything is gross to me. I’m really lost rn. I feel like I’m going to be one of those women who are sick the whole 40 weeks.
