Preeclampsia at 37 weeks??

I have had a headache almost everyday for 2 weeks & when i went to have my every two week check up my blood pressure went up to 114 from the usual 90 that it has always been through my whole pregnancy. All my doctor recommends is taking 1000mg of Tylenol. Can this be a sign of preeclampsia? I just feel like things are not normal. Also my right foot is always swollen hardly ever my left and ive had upper left back pain. Please help. FTM
