How nauseous is “nauseous” when it comes to morning sickness?

I’m not pregnant (knock on wood) just asking for future reference. You always see women on movies actually throwing up several times a day but I wonder. Six months ago I had an ulcer and woke up violently throwing up blood. The nausea with that incident was so bad it was hard to breath and if I could’ve walked down the stairs myself at the time I probably would’ve got the gun and ended it. It was extreme discomfort not even pain but like... nausea so bad its painful but not in a pain way?? I don’t even know how to put that lol. And it takes a lot for me to throw up. I spend a part of most days being moderately nauseous because of other health problems unrelated and they never make me throw up. Ive gotten motion sickness on twirly rides before but it never made me physically sick. So I want to know is THAT the kind of nausea I have to look forward to? The you’re bleeding out and about to die nausea? Or more of a mild “ew this ride is making me sick, bleh...” kind of nausea?
