I don't think so. I just heard about them on the news a couple weeks ago. But they said it could only predict weeks very early on, and after a certain point they were no longer accurate at predicting weeks. Still cool!
I read an article on yahoo about them. They were available in Europe but were just introduced to the states last month or the month before last, can't remember. They only read up to 3+ weeks though so you can only tell if you are really early not the exact week.
They had them in Canada, I used one. It's not very specific though, mine said "2-3 weeks." If you're any further along than that, it would just say "3+ weeks"
Also it runs on some type of battery or something so the display goes blank after like 24 hrs. I was glad I took a picture of it for a keepsake before it ran out.
Re: Did they have these around?
Edit i am in Canada too. Same as PP. They were available last year.
