Hi. I was trying to pull the blankets out from under where my husband had rolled over on them tonight and felt a pain like I had pulled a muscle. The problem is, I am 37 (38 on Monday) weeks pregnant and I felt the pulled muscle on my left side under my ribs, just above the naval. I was wondering if this could potentially be a problem. The pain went away for the most part in about 20 minutes or so with just some residual pain when I move wrong. Thank you
