Galactorrhea an early sign?

Starting a few days ago I started leaking a few drops of milk a day. I've also been throwing up after the first thing I eat after waking up. I've had breast tenderness but I'm leaning toward not counting that since I've gotten that after ovulation some months. I've also had some mild cramping but no period yet. My periods have been slightly irregular since my IUD came out in January so best guestimation for when it's due is between today and 4 days from now.
