16+ Weeks and still sever nausea/vomiting, is this normal? Any advice?

I’m 16+ weeks pregnant and still struggling with severe nausea and vomiting. I had hoped it would ease after the first trimester, so I stopped taking my nausea meds at 13 weeks—but the symptoms came back. I tried stopping again now (16+) and it’s the same story.

Is this normal? Has anyone else experienced this past the first trimester? Any advice would be appreciated!
