water broke after sex??

I am 40+ weeks pregnant and know that I'm dialated about 2-3cm. We just had sex and after when I went to the bathroom some transparent liquid came out of my vagina... I saw it coming out and feel that it was too  liquid to be sperm and I felt it was more than the amount of sperm that usually comes out after sex... 
could sex break my water? 
I after peed and it looked way more yellowish and was not so neutral smelling like the other thing coming out before... so it was def not pee 🤔
