Honestly if I'm not mistaken thats a sign of preterm labor so you should go to the doctor or hospital even though your considered full term I'd still go to the hospital
My doctor said to call if I get contractions that make me throw up,not BH... Your BH might be painful, but its not true labor so the hospital will not do anything. I would call your doctor and make sure they don't want you to go in.
I went into the hospital on Monday for contractions that were 4 minutes apart. They basically ended up slowing down while I was there and was sent home. I was totally nauseous the whole time and the nurse there barely cared... So it just depends.
