Preeclampsia worries

Has anyone else had preeclampsia? They say I don't have it but they're monitoring me every 3 days because I've had high blood pressure and protien in my urine. I'm so worried about my baby. He's measuring to 39 weeks but I'm only 35. So he's growing well . I've been having braxton Hicks contractions regularly but I haven't dropped at all.. Has anyone else experienced preeclampsia? I'm so worried :/
