What do you ladies think

38 weeks 4 days today.yestersay i woke up with sharp pains in my stomach like diarrhea pains but no diarrhea just mucus. Also Had an appointment yesterday, checked my cervix since I have been having contractions all last week, I was 3 cm, said cervix was still thick and hes -1 station. Had to have his heartbeat monitored cause it was beating super fast but was sent home, was told I was having contractions during too. Woke up this morning with horrible back pains and then eventually it went to one side and is still there, really hasn't gone away and at one point i was in agony. Been having more mucus today, had tiny bit of pink but this just happened. I think I have had a few contractions today but obviously nothing significant to time but I want to know what you all think and what's your guess on labor? Also this is baby #3 but it's been 5 years
