Increased blood pressure, but still normal (barely)

Cat

First of all I promise I'll ask my new midwife this question, just am in the process of a move and haven't had my first appointment yet, and I'd love to hear if anyone has any insight.

I've always had lowish blood pressure. It's pretty much always around 90/60, even throughout my last pregnancy. I was just looking at my charts from my former clinic and saw my BP was 120/70 the last time I was in. Granted it was a very stressful drive there that day, but I don't recall it ever being that high. Just curious if anyone has noticed different BPs with different pregnancies, and if everything turned out ok?
