My back for the last 2-3 weeks has been hurting horribly and getting worse day by day. I can't sit in the Chairs at school very long with out wanting to just cry cause I'm in so much pain and I can never find a comfortable position and night to lay in. It hurts so back. I am as if tomorrow 27 weeks pregnant. I've googled my back pain and it said i could be having preterm, and I'm so scared now cause I want my baby as healthy as she can be and I would feel so guilty. Why if it was because I missed a couple of my prenatal vitamins or something and it would be my fault my baby was sick. Is this a sign of preterm labor? Cause my back pain has gotten to the point where I don't even want to get up. It just hurts so much. And I've had hip pain too so both of them together are completely killing me. What should I do? I'm so worried!
