High BP

I'm currently 30 weeks. I went in last week for an appointment and got sent to the hospital for my BP. It was around 155/88. It went down once I got to the hospital so I was let go, and will now have weekly appointments. They were also worried about my liver as I had previously had episodes of pain and vomiting which resulted in an upper right quadrant ultrasound to scan my gallbladder which they found is fine but my liver is enlarged. Just curious if anyone else has had something similar? I know they're worried about pre-eclampsia since I had it with a previous pregnancy, has anyone been put on bp meds while pregnant? My last pregnancy this didn't happen until I was further along and they induced me at 39 weeks, so kind of nervous that it's happening so early this time.
