Worried about preterm delivery

Severe Braxton Hicks (still less than 8/hr), pressure in my pelvis that makes me have a serious waddle, and I feel like she's moved so that I'm carrying her lower than I have been, also really far forward in my belly and yet low in my pelvis at the same time. I'm 28 weeks exactly. My first daughter was born at 34 weeks, and I have a severe enough bicornuate uterus that I'm never expected to carry to term. Should I be worried? I've had high blood pressure and severe hyperemesis graviderm that has put my on bedrest/restricted work hours/physical limitations this pregnancy. I'm trying to not over stress, but I also don't want to push important symptoms aside, you know? I would appreciate any advice. I don't have another doctors appointment for 2 weeks
