I am 27 weeks pregnant. I have had a dull pain in my i right shoulder blade for about two weeks. Today while cleaning I bent down from the waist and almost got stuck due to an intense pain. Before today I was unable to sleep on the right side. I also currently suffer from anemia, ulcers, and acid reflux. I don't know if the pain is related. For the past three weeks I have also noticed that I am extremely fatigued more than normal but also can't sleep at night due to pain.
