Why do I have kicking feeling like a have a baby inside of me? It normal to feel that way? (photo)

You need an IN PERSON examination with possible ultrasound scan... Over the internet we can not examine you... 

Pain, pulling, and tugging
along the incision quite common after tummy tuck surgery. The discomfort
can get worse a few weeks after surgery as some of the nerves start to wake up
and work again. Pain can also increase because at three weeks out patients start
to get more active once again.

Sometimes the pain is
caused by tugging of a stitch that will eventually dissolve, sometimes it
can be caused by scar tissue. Generally these aches and pains and zings
will come and go for a few months after surgery, but usually they resolve.

You may feel more
comfortable if you speak to your plastic surgeon directly. He or she
should be the one to recommend medication to you.

My best guess is that you are experiencing muscle spasm. If so, use of muscle relaxants may be helpful to you. Best to follow up with your plastic surgeon will be the best position to advise and/or reassure you. Best wishes.
