hi ladies, I'll be 16 weeks Wednesday and I just out of the blue popped!! seriously like in 2 days I went from barely bump to filling my new maternity jeans lol. anyways, with that I noticed lower back pain and tonight I'm hurting bad. I took tylenol 3 because it's that bad... I was wondering if any of you were told by your dr to use a heating pad? thanks in advance :)
