Yes it is normal. Your baby has limited space hence movement will be very much minimal. So when baby toss,turn,kick you will feel uncomfortable or pain. Plus your body preparing for labour at this very last lap. There are people that experience sciatica which is the pain from the butt, nerves till it is hard for you to step on the ground. You can do massage, light stretching to ease pain. You can also out cushion when you rest/seat.
