A long as you count 8-10 movements in an hour you should be fine but definitely call your doc if you're concerned.
Really cuz the books i read said the baby should be kicking more which isn't what my daughter is doing, but when she does she kicks hard lol
If your concerned with the movement. Drink a big cold glass of something sweet like juice or even water will work then lay down and see if that gets ur baby moving. The farther along u r the less they actually kick cuz of less space they just move around n stretch, well with my pregnancies that happened anyway. I am on baby #5..
