Exercise ball triggered Braxton Hicks :(

RL

I just got an exercise ball and I was (very) gently bouncing and swaying on it for about 10 minutes and now I've got Braxton hicks every 5 minutes. I've had these back to back contractions a lot before (monitored at 28w and 31w) and they haven't triggered labor at all. I'm 34 weeks. Also the baby moved from lying on my left side to my right. I have such a sensitive uterus :(
