What does nausea feel like?

Destiny • I`m 23 living in London TTC baby #1
This morning I woke up with this feeling at the back of my throat as if I wanted to puke. It goes and come back probably every min. I tried chewing up but that hasn't helped. 
​And I think I'm bloated lol I'm not sure, I feel something on my tummy as if it's bubbles. 
​Anyone experiencing or can help me?
