How soon is too soon?

So I met my now boyfriend a month ago (met as in met in person) and we have been dating for two weeks now... we're moving pretty fast I suppose, as in already talking about future plans, moving in together when we can afford a new place, marriage, babies, but it doesn't feel like it's been such a short time. We've been together everyday except 4 days, since we met, so we've spent quite a while together. The past few nights we've been together I catch myself almost telling him I love him!! I'll be laughing with him, or looking at him and I'll go "I lo-... I can't get enough of you" and I'm not even meaning to say it, it's just coming out, then I stop myself before it's too late. I've been in many relationships, and none of them ever felt this right. Also (sounds crazy) for years I've been doing the ring test, where you see the amount/gender of kids you'll have, and it's always been right for others, and I get the same thing every time I do it on myself, and when I do it on him it says we'll both have three girls, which gives me a strange feeling of hope that he's the right one. Am I crazy? I don't really plan on telling him I love him yet, but how soon is too soon? I feel like sometimes you just know, when it's right, it's right!!!
