Yep, I agree with the others. As long as you are still feeling her move regularly, everything should be alright. The pains come and go, too.
I agree totally with Alaysha.
Because it is so cramped inside baby prob doesnt have enough room to be making big movements any more. Plus babys just like adults have days of being tired and not really wanting to do anything as well. As long as during her most active hour you feel 10+ movements than everything should be fine. But if you are still worried contact your doctor.
