HI, I understand your concern. * If you are already a patient of high blood pressure, you should inform your treating doctor about your pregnancy .. so that he can change you treatment with a safer drug. * If the BP is raised with pregnancy, High Blood pressure in a single reading can be due to temporary physical/ psychological stress. SO Repeated recording of blood pressure showing raised Bp is confirmatory . you will be given expectant treatment ( rest, have stress free life, try pranayama/ meditation for mind concentration./ avoid excess salt,alcohole, late nights, smoking,..) If not controlled with this a regular treatment/ regular checkups of urine & weight gain are kept. USG is done to monitor fetal development .. and with these & regular medication, pregnancy can be taken to term & child birth . In short, don t be concerned, visit your doctor & follow the instructions given You will be alright. thanks,
