nervous, help me please!

Alright, my boyfriend and I are not trying to have a baby right now. We haven't had sex in over a month, we've been traveling and working, out of nowhere my breast feel very heavy, and they have discharged something white (not liquid), they hurt, I've had some pain below my breast as well. I feel kind of bloated as well. Btw, I haven't had my period either, was suppose to come on the 21st, nothing, got it in December though. Taking a pregnancy test soon, but in the mean time can someone give me their thoughts?
