I'm having white liquid(discharge) when I squeeze on either of my breasts. My breast are also sore, and every once in a while my stomach will "vibrate" and occasionally I will get pain in my stomach. I've been experiencing this for a few weeks now and my period was very lite and was only 3days compared to a usual 5-7 days. I've been super tired and bloated and it hurts if I suck In( flex) my stomach at any time.    What could this mean ? I'm not sure what to do about this particular situation.
