I tried this also just for fun it did nothing the first time. Fizzes like a beer the second time and then nothing again the third time. Lol guess I'll see in 13 days thats when I find out.
As soon as i put it in it didn't fizz or anything. Lol and im 15 weeks and a day(: i still havent seen my baby at all.
Its right away. You're not supposed to wait. And I did that it was wrong for me.
They say its just for fun but I tried it just for the fun of it and mine fizzed a lot. Lol I guess we just have to wait for that U/S ;) how far are you now ?
