The first few months of a pregnancy are the worst for me- I have never made it full term so I cannot comment on what the last 2 are like- full disclosure.
The first few are just awful. Everything smells. Badly. I can't think of a single thing that smells good to me. Everything makes me retch and heave. I hold my breath when opening the refrigerator. I make non-smelly things for food- such as cereal (who says you can't eat it three times a day).
But unless I have told people there is no way that anyone would know I am pregnant. I am not showing, I just am a bit more chunky, so I can't play up the pregnant person sympathy.
Grocery shopping is an exercise in control over my gag reflex. Just walking in to the store I am bombarded by a hundred different odors each more nauseating than the last, so shopping is done at a full out sprint most of the time.
This is actually an improvement. I required IV re-hydration last week as for several days I could not keep even fluids down. Now that I am staying ahead of the nausea with lots of medication hopefully I can expand my diet to include more than lemon ice soon.
