BH contractions are getting real

I've had BH for 6 months minimum but the were just uncomfortable and my belly would tighten. But now they feel like period cramps or I feel them in my back and they last at least a few minutes. At least 6 a day for the last several days and strong enough to wake me up at night.

Unlike what dr Google says, they do not go away if i change positions. Im only 36 +3 and a FTM so statistically baby won't make her arrival until closer to 8 days after her due date. But I'm afraid O won't know when labor starts and when to call my doula. Once the doula gets here I feel confident that she will get me to the birthing center and my midwife in time. But my doula lives 3 hours away so I'm afraid labor will sneak up on me!
