I am 12 weeks pregnant with high blood pressure: Advice?

I’m 12 weeks pregnant. I went to my first gynecologist appointment last week, and my blood pressure was a little high, so I was given medication to treat it, this is my second pregnancy on my previous one, i developed blood pressure at 36 weeks, and i had c section due to fetal distress so I’m scared that history will repeat its self so if the is any advice that you mums can give me or if someone is facing the same situation as me any advice will be appreciated
