Anyone have high blood pressure in early pregnancy. Did you take any medication for it?

Pre-preg my BP was borderline high. With DS my BP was high after 36wks, but I was just put on bed rest, no meds

I'm 7 wks now and dr prescribed aldomet which is category B. Reading about potential side effects scare me, esp the depression and anxiety. I'm also wondering if there's anything category A.
