I am very surprised that your doctor has not been more proactive about your rising blood pressure. Have you been monitoring your blood pressure at home? My blood pressure is usually higher in the doctor's office so my doctor goes by my home readings, which are consistently in an OK range. I don't know about the standards for diagnosing preeclampsia in Sweden (I assume by your user name that you are in Sweden.. is that correct?), but 145/95 is considered high for pregnancy here in the US, and 150/105 is very high. I think it is a good thing your doctor wants you to go on BP meds, but I also think you need to be monitored more closely with blood pressures that high. Have you done a 24-hour urine test, or just the office single dip tests? The office tests are not as reliable as a 24-hour catch, and here in the US the result of the 24-hour test is one of the factors used to determine if you have preeclampsia. Are you able to go to labor and delivery at the hospital and be evaluated by the physicians/midwives there?
