Congratulations!!!
I don't want to put a downer on the proceedings but dont get your hopes up too high until the 12week/3month mark is reached. Me and my GF found out we were expecting about 4 weeks ago, but we lost it to a miscarriage last week -about the 9-10 week mark.

Apparently it's quite common but once the 12 week point is reached and it's fully developed and it just has to grow then as long as no serious illness or trauma happens mother and baby will be fine. So we'll be trying again!!
So best of luck !!!
Later..
