we don't have a scale, so i have no idea where exactly i started or where i am now, but i'm definitely in early maternity pants (these pants definitely fall off my butt when there isn't any extra weight around). i'll just be 8 wks this weekend, so yea, it seems bizarrely early for me too -- i didn't need maternity clothes until well after 20 wks last time.
as far as eating "healthy" goes.. i try to consider that whatever it is my body is asking for is "healthy" -- even if normally i would never eat such a meal and call it so (for example, on sunday this week i had five pieces of bread slathered
with butter, two spoonfuls of bean salad, and a boatload of watermelon. not UNhealthy, per se, but.. pretty far off my normal fare). i do tend to avoid very sugary things (easy enough anyway, since most sweet stuff totally turns my stomach) and we dont' have anything with high fructose corn syrup in the house, but the other day i did eat a bunch of fritos 'cause i needed a snack and they were the only thing we had around that would do.
eating for me is my least favorite part of pregnancy. everything is just so OFF from my normal diet and i have a hard time coming to terms with the craziness that my body seems to need. but i almost always feel so much better when i listen to what my body is telling me, so i just try not to get TOO hung up.
hope the first trimester goes quick for you and maybe things will settle down and you'll feel better about the whole situation
CONGRATS on quitting smoking, by the way! that is AWESOME! my partner quit when i was 7 months pregnant with DS and it was HARD but it's been SO GREAT for all of us! and yea, he put on a little weight from it too, but man it is better than cigarette stink for sure!
