Is this practice or getting closer FTM

Last night trying to go to bed but I started having some REALLY bad contractions. Started trying to track them. The app would sometimes freeze up so the ones saying "2 minutes" weren't really two minutes and I did have one between the 10 min ones. My BP spiked to 144/96 this went on for about an hour but because they were only 6 minutes apart I just drank more water and went and took a long hot shower they started to subside so I finally fell asleep because they weren't so bad but I was exhausted. I'm good this morning BP is back to normal. But do I tell my doctors about this? I have an appointment tomorrow afternoon.
