When did you call the doctor?!

Kat • Pregnant with baby #3
I'm 39 weeks 3 days and I keep having strong Braxton hicks contractions. Last night they were 10 minutes apart and went away after 2 hours.. I woke up around 3:30 this morning with cramping and backache. Today I've had strong BH and loose stool. This is my second pregnancy and with my first I mainly had cramps the day I went in the hospital. Just wondering when you ladies called the doctor or went into labor? If you all had any of these symptoms before? I'm getting so anxious!!
