24/7 nausea

I’m currently at 6 weeks pregnant, I’ve been having nausea & dry heaving 24/7 even when I’m sleeping I feel like I want to vomit but I can’t. I just want to be in bed most of the time cause I feel sick, today even drinking water makes me want to puke. It’s annoying cause I want to puke but there’s nothing coming out. Is there any pills or remedies for this?
