Sleep at 28 weeks

=[ this girl over here loves sleep, I used to be able to sleep for 12 hours comfortably. Well now I wake up every two hours and get at most six hours of sleep. My shoulders are killing me from sleeping on my side, I have a body pillow, I put it in between my knees. Nothing is working ladies, my body aches! I have to work all day and was up very early. I'm desperate for sleep. Any suggestions or anyone else with similar sleep experience right now?
