Frustrated.

Today I had an appt with my OB. I've been having a large number of BH contractions each hour and loose stools as well as lower back pain. I asked if I could be checked for dilation as I'm now 34+1. They didn't think it was necessary to check. I've been home all day with cramping non stop and still having a lot of BH contractions even at rest. Is this ptlbr?
