when you keep a fight with your DH going until 3 am - 5 hours total. Yeah, next day I decided it was time to buy a preg test.
when you eat healthy, take all your vitamins, exercise, get 8 hours sleep, and you still feel comatose.
when your 4 year old walks up and informs you, in a most distraught voice, that you need two babies and we only have one. We haven't told him yet, but I think children are very perceptive.
when you eat a very satisfying meal and have plenty of water all day, but then 20 min. later stand up and almost black out.
when you look for your pregnancy books on the bookshelf, can't find them, so you go through every single box of books in storage, only to find they were on the bookshelf the whole time!
