High blood pressure?!

I went in to L&D tonight thinking I was in labor but my contractions weren't dilating me at all. I'm 38+5 weeks and they realized my blood pressure was high, reading anywhere from 130/90-165/103. They ran some blood work and checked my urine and said everything looked perfect and to follow up tomorrow with my OB. When I got home I started looking on the not - so- informative internet and started getting worried. Has anyone had experience with this? If so, what did they do?
