ahh,bless you!!congratulations!!!!
i thought this was going to be about passing the time in the last few weeks...i've got under a week to go and am most impatient person ever!!
i really don't think there's much you can do to wish the 12 week mark on.
i'm pretty sure i told my parents,brother,and best friends the day i found out!so you've been very restrained so far.
just make sure you've got somwhere to go everyday,or a task to do..some gentle cleaning etc
you'll find that you now wait for certain stages for years..the bump to show,the first kick,the hiccups,the birth...the first time they,smile, roll over,crawl,walk,talk...it's always something!!
i suppose my advice then,is not to wish it on,but to savour the moment.
good luck and congrats again
