Why am I wet?!

Ladies..help! How come the past 2 days I keep getting round wet spots in my panties? To the point where I need to change them. They are round wet circles? What does this mean? I came off of the pill on the 11th for the 1st time in 8 years! We are ttc but my body is doing funny things..like these wet spots and I have been having cramps! We have been doing the bd like every other day because I don't know when I'm ovulating.. please help me!
