Does Nuvaring cause Lactation?

Someone help- I've been on the nuvaring as my form of birth control for not even half a month now, and just today I noticed I'm kind of lactating a bit.

It's kinda terrifying since I've had sex before birth control and had to use plan B? I haven't been sexualy active long enough to be lactating if I got pregnant, though.

Does someone have an answer? Is this just a hormone thing?

I'm kind of freaking out :(
