Horrible Braxton Hicks

So today around 2 pm I was having the worst contractions. I kept changing my position and drinking water but they still remained. Idk if it was in my mind they never subsided but they felt constant. I decided to try to relax in the bath but I got so dizzy I had to get out and lay back down soaking wet in my bed for about 5 mins. I had been sweating like a pig so I really wanted to shower so I tried the bath again but I was so dizzy and in so much pain I was shaking. I couldn’t sit there for very long so I washed up really fast and got out. I dried off laid back down texted my mom and boyfriend and slowly but surely they went away. They were SO INTENSE! I’m only 36 weeks and I feel like baby could cook just a little longer. I’m a FTM and I was alone so I was a little scared! Is this normal? Did any of you ladies have similar experiences?
