17 weeks and already leaking colostrum?!

Hi ladies!
I'm 17 weeks and 4 days (with my first child) and today I had this weird urge that wanted to check to see if my body was producing colostrum yet and low and behold it was.
It's a white slightly milky colour and oozes out whenever my breasts are touched or stimulated. My nipples have also started aching since I discovered this.
Any one else in the same boat?
