braxton hicks, ultrasound, baby facing back, less movement.

So I've been experiencing alot of braxton hicks. Some hurt and some are uncomfortable. I drink plenty of water but I still get them alot.

Last time I had an ultrasound and my baby boy was facing towards the back. I've been feeling less movement. I still feel him move but not those hard kicks. Also been experiencing some uncomfortable back pain. In my lower back. Can it be because he's facing the back?. I'm 28 weeks by the way. Getting worried! But scared to call my DR. Since he's always in a bad mood :/
