I am a little over 18 weeks pregnant. When I feel the baby move it is the lower left side . When they have been able to get the heartbeat it has been the same area. I have slight back pain on the left side. When I look up the difference of anterior and prosterior , I am confused to which it may be. any ideas?? Thanks!
