Baby moving

Ok so I've had one and movement wise I've felt the flutters since 11weeks ish I'm now 14. I was walking to bed one night and I felt this crazy pain in my lower abdomen. It felt like baby did a flip it hurt so bad it doubled me over. I never felt that or any movement that strong with my first. I didn't start bleeding or anything and have felt the baby stronger since. Have you ladies felt anything like this or are you guys feeling the baby move at all yet?
