Movement?!?!?!?!

I have been really anxious about feeling movement. I know it is early, and that I won't feel it all the time or even everyday. Last week while shopping I had a stupid defective cart. I ended up pulling something in my back and abs area. I ended up cramping, it was horrible. I did nothing for a whole day per nurses' orders and it helped a little. Since then I have been a little worried. I really want to feel movement and have vegged out most of the day with the kids hoping to feel something, but nope. Then tonight I am sitting there watching K-9. I had given up on feeling anything today and then pop, is that the baby? No, it couldn't be. I have 3 kids I should know for sure what is the baby moving right? Back to the movie...a few minutes later again! WOOHOO!!! There really is a baby in there!
