No matter how hard I try I cannot get comfortable sleeping on either side. My shoulder/upper back starts to ache almost immediately and I end up turning to the back position. Then I basically get worried that I'm on my back and toss and turn and end up hardly sleeping. Anyone else having these issues? I'm 19 weeks along. I'm worried that laying on my back will hurt the baby but it's seriously the only comfy position for me. My shoulders are in such an awkward position when I attempt to sleep on my side. I'm not sure what to do. Any suggestions are greatly appreciated. Thank you!
