Labor near?

Danielle • Happily married and expecting a little boy to be born via c section on March 9th!
Ive been having this feeling that labor is going to happen soon even though it's too early! I've had a lot of cramps, back pain, and diarrhea. I went to the doctor and she said that my cervix is still high and closed. I'm getting a cervical ultrasound soon but I wanna know if maybe I'm just sick or crazy. Any advice?
