congrats on your pregnancy!
im 25weeks along, i was like you laid back before pregnancy, but started worrying about things more now that im pregnant! lol like newmommy said, its normal the first time around:)
i had bad morning sickness for the first 3 months, it hit right at christmas, i couldn't keep a thing down for a while, even water came up sometimes, but it got better
For some women morning sickness lasts for the first 3 months, i get alittle sick now and then if i ate something that didnt sit right.
Anyways congrats again, make sure to take your vitamins:)
