How long were you trying Jenna? You must be thrilled if a little over whelmed which is totally normal of course, as far as I can gather being pregnant makes every emotion totally normal, from elation, depression, tears, giggles etc etc!!
I got a scan at six weeks coz I was spotting, and I still cant quite believe it. I dont really feel sick tho, I kinda wish I did because it would remind me i am pregnant, if you know what I mean.
