Braxton Hicks?!!

Okay so I’m 34 weeks but I have more amniotic fluid and stomach measuring 38 weeks already! Baby is in 80th percentile and is head downand I was getting a stress test done and the women doing it showed that I was having Braxton Hicks and I was like oh that’s what that is. I thought the baby would move a certain way and make my stomach tight. So I been having them since 27 weeks. Welll today they have been minutes apart. I think they are just Braxton Hicks cause I don’t have back pain. But they last a long time and come really quick. Has anyone else had this or what do you think 😞 and what can I do to help it. I even took a long shower and they lasted throughout shower
