Advice?

I'm 29 weeks and 2 days. My ankle gave out on me earlier this morning in the middle of me walking. My feet bent backwards leaving a big black bruise on the front of my ankles and I landed on my hands a knees. I've been having really bad Braxton hicks since it happened (only 2 or 3 an hour). My baby is still moving around like he usually does but my Braxton hicks have been to the point where I have to curl up in a ball and they leave me in tears. Could the fall have caused my Braxton hicks to be this bad?
