post-baby body

is anyone else freaking out about their post-baby body? i've been kinda fit and slim all my life, even too skinny at times, and now at 12 weeks i am starting to freak out about my growing body, the boobs, the belly, everything is getting so big. i am having a really difficult time realizing that my body has changed so much in such a short time, i cry often because of it. i love my baby to bits, and we waited for years for it, but now i'm confused over the love for my baby and love for my body.
