Contractions?

Peyton

I was laying down and went to go wash some dishes and in the middle of washing them all the sudden I got this intense amount of pressure that I’ve never felt before so bad that I had to bend over and I couldn’t even stand up straight , I’m not sure if it was a contraction or not , I’m 34 weeks and 6 days. How am I supposed to know when I’m having contractions? I’m a first time mom
