Should I contact my doctor, or is it just a waste of time?

I am 38+5 weeks and had my third “episode” of what I thought might be early labor last night. I tried to go to bed around 10pm & just laid in my recliner ...slept for about 2 hours & woke up to pee. After that, I didn’t sleep from 12am-5:30am because I kept having mild to moderate contractions that seemed consistent & were lasting 1-3 minutes, coming & going every 10 mins or so. I tried changing positions, walking, rocking on exercise ball...nothing made them go away, but they weren’t necessarily getting any worse. Then around 5am they stopped. This is the third time this has happened to me & it is just so frustrating that I cannot sleep & labor is not even coming 🤦🏽‍♀️ I’ve had mild period-like cramping all morning since I woke up at 6am, but not any more time-able contractions. I am getting so discouraged & just want to have my baby already. Is it even worth it to call my OB & tell them about my symptoms? I don’t think they would do anything since I’m not in labor, but it’s just so frustrating to me that there’s nothing I can do. I lost mucous plug & had bloody show with it at 36 1/2 weeks, and a week ago I was 2cm dilated & 80% effaced.
