any other mamas with high blood pressure?

Hi ladies I'm almost 27 weeks and my blood pressure has been pretty high since about 22 weeks. It's averaging 160/100 even at home. I have no swelling and no protein in my urine and so far my blood tests look fine. My baby is measuring 2 weeks behind but she is weighing just fine. I'm hoping I don't get preeclampsia. I also have slightly high bp before getting pregnant but never this high. I'm just curious if anyone is dealing with this in their second trimester. I am on labetalol 200mg 2x's a day and my pressures are still averaging on the high side. I'm hoping I can hold out till at least 35 weeks.
