I’m almost 21 weeks so I’m at the point where back sleeping is no longer 100 percent safe. Last night I put pillows behind my back and pregnancy pillow in the front and slept on my side all night. This morning I woke up with cramps, cramps went away but I have occasional sharp lower pelvic pain and lower back pain on the left side for the back. I’m trying to avoid the doctor bc I don’t think it’s baby related but sleep related. Is sleeping on the left side painful for anyone else?
