Movement! Movement!

My little peanut has been moving around like crazy. I feel little flutters, especially at night. So I decided to put my hand where she/he was moving and I felt it from the outside. Is that possible? I thought you couldn't until around 20 weeks or so. I'm 18w2d :)
Anyone else experience this ?
