Anyone known they were pregnant before missed period or testing?

Hey ladies. Im curious to know if there are any of you out there who "knew" they were pregnant before a missed period or taking a test. Like just had that 'feeling'. My mother says she knew from the night of conception. She just had strong feelings, and she happened to be right! Id love to hear your stories. I feel a little crazy but this past week I feel different. A/F isnt due until 4/16. Baby #2 for christmas? lol
