question: I am 17 weeks pregnant and keep getting a feeling like a really hard kick in my upper abdomen. I know it is not the baby. When it happens, it happens once quickly, but is hard enough to surprise me and feels very weird. Today it almost took my breath away. This is my fourth pregnancy. It did not occur with the first two. A few times with the last one. This is occuring much more frequently with this one. I am now feeling the baby in the lower abdomen and can say without a doubt it is not the baby. I have read about abdominal muscle spasms - only this is not twitching. Does this sound familiar at all?
