Constant Nausea & Awful taste in mouth!

Britney
All day nausea hit HARD this past Friday. I barely left my bed all weekend & getting through work days has been a bear this week. Nothing sounds good to eat & when i do eat I can barely get it down. Plus afterwards I have an awful taste in my mouth & burp ? it up for hours. And don't have even get me started on the extreme fatigue & constipation!! 
Healthy babies right?!?! Anyone else?
