Impossible??

Amanda
I'm laying here flat on my back and out of nowhere I felt a familiar sensation. I stopped and looked down and I saw little pops! I'm 12 weeks and this is my 3rd pregnancy, but sadly i only have one living child. My last baby I had to give birth at 21 weeks. But I do know the sensation of a baby moving. I just want to know if I'm crazy and if it is even possible to see and feel baby this early, because I have never felt it this early before, I just assume I'm nuts!
