Pregnancy Induced Hypertension

My 37 week appointment was today and my blood pressure was high, 156/96. It's normally 120/70 during pregnancy. I told the doc I've had headaches the last week, but I have no protein in my urine and no swelling so it's not pre-eclampsia. They want me to call if I continue getting headaches over the next several days and they'll have me come back in and get checked. I'm just wondering if anyone else had it without it turning into pre-eclampsia and what your doctor did about it, like did they induce or give you meds or what?
