Rough sex and labor?

FTM Here. My husband and I had some pretty rough sex earlier today. Since then, I've been leaking something (not sure if it's amniotic fluid or discharge, it's water but I can't really tell if it has a smell) pretty consistently, but not a lot. I'm 32+3 weeks, baby is really low too. Like so low I feel like any time I sneeze or stand up, she's gonna come popping out. I'm having some lower back pain that started up after the sex too. Am I right to be worried that this could be the start of labor or is this pretty standard after having sex in the third trimester?
