You won't neccessarily get pre eclampsia ( esp if you didn't have it the first time).
Some people get gestational hypertension ( high bp in pregnancy) and some have an underlying predisposition as Sloane said.
Your Dr will be monitoring your bloods etc and growth of baby, you may need to be induced early if babies growth slows but heaps of people are on BP meds through pregnancy and go to term or near term. there would have to be major problems for them to do anything now. I see lots of patients whose BP is controlled by tablets so good luck hun xx
