Should I call my doc??

Tay

26+4 weeks here. Two days ago I had mild cramping that I put to be Braxton Hicks. One in the morning and one in the evening. In the middle of the night last night I had low back pain that just remained dull and lasted what I think was about 15-30 minutes. I wasn’t nervous with the cramps but with the low back pain, I got a little nervous. Do you guys think this warrants a call to the ob/gyn? Thanks!
