Water broke at L&D

Cianne
I went into L&D for contractions. They weren't close enough to count so I got sent home, but before I did she checked to see how dilated I was. I'm 36 weeks and 4 days. After she checked me it got super wet down there like dripping on the pad and then my underwear were soaked on the way home. Could she have made my water leak by checking? I'm 3 cm dilated and 50% effaced.. and gave been losing my mucus plug.
