I am 13 weeks and 4 days! I am a very tiny person, in my eyes at least. I am 18years old and 5'1. I weigh only 94.8 pounds! I was laying in bed and got this quick small pain on my right side on my tummy kinda near my belly button. It is gone now but I was wondering do baby's move this early on to the point that I could feel it!??!
