Cally, if you click on the tickers in someone's signature, they will take you to the website where you can make your own. Mine is for marriage, but there are tons of pregnancy ones as well on Lily-pie!
I'm due sometime in early July - my cycles are a bit unpredictable, so I'm not sure when. I'm currently 4-5 weeks pregnant!
I'm planning a Christmas reveal as well - I think I'll tell immediate family a week or so earlier. I'd love to wait and surprise my parents and siblings on Christmas, but I want to tell them before the rest of the family, and it's pretty much only Christmas and Thanksgiving that the whole family is together. Hopefully I'll have an ultrasound pic by then. I'd like to wrap it and have my nana open it up on Christmas!
