Extreme nausea

I’m 6 weeks and 2 days and for the last 4 days I’ve had extreme nausea all day that has left me bed bound. I have only vomited once or a twice a day and I’m managing to drink and eat small amounts. The nausea is so horrific it hits me as soon as I wake in the morning. This is my first pregnancy so I’m not sure if it’s normal, my poor hubby is googling everything and is so worried that I shouldn’t be this sick. I’ve tried vitamin b6 which hasn’t helped. Should I be worried and make an appt to see a dr?
