morning sickness?

can morning sickness start in the second trimester? at 16 weeks? i hope not. i hope what i am feeling is just a fluke, a virus, a little under the weather....hoping it has nothing to do with the path to a new baby.....i hope it is not the start of morning sickness.
for the last three to five days (or something like that, im trying not to remember exactly), ive been waking in the morning feeling terribly nauseous....and i chew gum or have a mint, and i eat breakfast and im generally fine, until some scent sets me off, and im nauseous again.
today has been the worst. i was nauseous this morning, but then we went out to breakfast and i figured once i had eaten, i would be fine....but after breakfast that feeling came back within 30 minutes. in the grocery store, i couldnt help pick out any produce because it all smelled bad to me, and i even took a little produce bag and put it in my pocket just in case....(thankfully no need to use it).
when we came home, i tried to make plans to go shopping, again thinking that i would feel a bit better after eating lunch.....wrong again. worse!!! so i cancelled the plans i had made 30 minutes prior (sorry jami!).
my biggest problems right now are the fridge and the dishwasher. i cant open either one without gagging.....so, my wonderful husband is going to clean out the fridge today to make sure it's spotless and fresh without any old or smelly food....and im the one who normally loads and empties the dishwasher, so who knows what is going to happen now. i guess if there are dirty dishes in the sink or on the counter, i wont be able to go into the kitchen at all and that will be even worse! maybe i should just suck it up, gag a bit, and do the dishes.....or else, we all know, they wont get done.....
the weird thing is that normally chewing gum or popping mints really helps me...BUT, now i put a mint in my mouth or start chewing a piece of gum and i feel like im going to gag on it, and i have to take it out. i have to hold my gum in my hand, chew a little, and then put it back in my hand.....i know- im weird. hopefully this stage passes quickly....
