What's considered a good blood pressure?

So normally my blood pressure has always been considered normal 122/81 according to doctors they will say " that's good " so recently I have been showing pregnancy symptoms and twice already my blood pressure was high even my first doctor said it wasn't good and it was like 130 ( I forgot the bottom ) but today I went to see my OB and my blood pressure was 130/83. Now I was ready for her to say, " that's not good " but instead she said that was good. I thought anything over 120 was considered high?
