I almost never felt my first until my last month. Every night, I would drink a big glass of ice water (quickly, but don't give yourself a brain freeze) then I would lay still. That is when I would feel her move. Give that a try. If you still don't feel anything, call the doctor.
The pains are probably you growing thats what my dr told me I get stabbing pains on my left side for the most part and every once in a while on my right side and she told me that it was going to continue to happen because the baby is moving up and growing she said it was normal
