nausea not going away?

Erin
So I'll be 12 weeks tomorrow, and I was really hoping my nausea would be going away, but... it's actually gotten worse in the last week or so! :/ Not throwing up, just nauseous ALL DAY LONG. Have actually lost a few pounds because I have zero appetite. Taking unisom/ B6 combo at night, which helps, but I'm just SO ready to start feeling better. Anyone else around the 12 week mark and still nauseous?
