Water break?

Sorry if it is TMI. I went to n°2 and while making some effort I felt a lot of liquid coming out. I though it was pee because of the effort but it was more than usual. I think I could stop it contracting. When I wiped I also saw a bit of mucus plug ( not bloody just thick transparent mucus). Then not more leaking . I was wondering if in case my waters broke while.in the toilet I would leak a bit after right ? I walked for more than an hour an nothing else coming out ... Thanks in advance ( I'm 39 weeks ) .
