What does pregnancy nausea feel like?

Janelle
At this point, idk if I could actually be pregnant or if I'm just having pseudocyesis. I find myself always gagging and randomly feeling like I'm about to puke. Like I could be in the middle of a conversation and then have to stop talking because I feel like I'm about to throw up but not because I ate the wrong thing or something, it's just random. But I don't think that's the same thing as "nauseousness" right? When you're pregnant and nauseous, doesn't your stomach hurt like it would if you had a stomachache, followed by  feeling like you're about to vomit, and then most likely vomiting? Or is it random like I described?
