Sleep/back pain


Ever since about 30 weeks (now at 33) I’ve been experiencing progressively worse back pain. Now it’s to the point where I can’t hardly put any pressure on my left leg w/o taking Tylenol. I try stretches & pillows & am going to try a heating pad once I get one but it’s becoming unbearable. It also is causing me so much discomfort in my sleep that I wake up on my back. I’m terrified I’m going to hurt my baby bc I heard it’s bad for their breathing!! Anyone have any advice/tips/input? 😔
