6 weeks pregnant and can't sleep

Emma
Just found out a week ago I'm pregnant with my first child.. I don't have any Morning sickness just sore breast. But at night I have a terrible back ache and leg aches that will wake me up in the middle of the night. It's to the point all I do is toss and turn. I can't lay on my stomach because my breast hurt so bad. Any ideas on what I can do? I can't sleep at night anymore so I'm exausted all day. Advice?
Thank you 👶🏼💕
