Milky Boobs

Starting last week, I noticed that a few bays before my period my breast would start leaking milk. This week, though, my breast have grown one bra size and are more sore than I remember last week and more milk is coming out. I took Plan B last week after I had sex but I'm freaking out now and thinking I might be pregnant. I'm supposed to get my period tomorrow and so far I don't feel it coming 😡😑😅😥😤😰😩 super scared
