Mothers Intuition Pre-Pregnancy Test?

For those of you who found out early, before testing did you just "know" you were pregnant? Some studies show that some women have claimed to just know, deep down, that they were pregnant. Before having a late period. Although most of the women on here were TTC before becoming pregnant, did you still know that this was it? That this time you had finally achieved making your bundle of joy? Feel free to comment and share your story on how you found out and your reaction to finding out (surprised, happy, I already knew, the whole works) Everyone has a different story, although they may be close to the same I'd still love to hear all of them (:
