"Breast milk" and not pregnant...

My period isn't due for another 10 days. My husband and I are trying to conceive but not making a huge deal to stress over it. I woke up yesterday and my breasts were super sore! This morning same thing and they are staying sore. So, I tried rubbing the soreness out like you would a muscle and I had "breast milk" come from both nipples. It was clearish at first then milky white. I will be 26 Friday. Has anyone else experienced this and know what's going on?
