Hello, do you know anything about this? My stomach is upset and hurts like period cramps, it's been hurting in my belly. I had an appointment at 5:00 PM, I asked for a dilation check-up. The doctor said 2.5 cm dilation, but the cervix is still long. While driving home, I felt like contractions. It's calmed down now. Is that close to labor or not?
