37 weeks and 2 days....extreme back pain and cramping.

Katie
Today I am 37 weeks and 2 days. I am having unbearable back pain and abdominal cramping. I don't think any contractions and no water has broken. Is this the start of labor??? This pain is OMG level pain. 😔How am I going to get through labor??  I see the doctor at 2 tomorrow so I am going to tough through it but thought I'd asked experienced moms out there...is this how your labor started?? Holy crap so uncomfortable!
