Yup. MS doesn't always just come on in a wave of you running to the bathroom. Amazing what TV and movies drill into our heads.

I felt mildly nauseous occasionally until 8 weeks, when I started just feeling terribly queasy all day, coupled with praying to the porcelain god once a day.
Welcome to the wonderful world.
Might I suggest a few things?
Ginger ale and saltines are your new best friends. Embrace them.
Preggie Pop Drops are all right for mild nausea. But if you feel like you're about to lose your lunch, honestly the best thing to do is just get to the nearest bathroom and get it over with. Throwing up sucks. We know. And if you're like me, your insides will spasm for a good minute or two after, you'll chill on the bathroom floor with tears running down your face, and feel weak for the next five to ten. But after a couple minutes you can clean up and it'll be a memory. Fight it back and you'll just be nauseous all day.
Sea-Bands are great (for most people, not all) for the all-day queasies.
Ginger gum is good for chewing to stave off nausea as well.
And when you get up to pee at night, eat something. I keep string cheese for this very reason. I've been told that drinking some milk can do the same. Nausea hits when your stomach is empty...keep it from getting empty! Keep crackers or something light with you at all times, and nibble at the first sign of an empty stomach.
Good luck!
