Am i filling with milk yet not pregnant?

Have all tall tell signs of early pregnancy and today my boobs ache like ive been repeatedly punced in them. Especially the left one. While checking my holes from piercings i took out i noticed my nipple was moist and curiosity got the best of me so i squeezed my nipple and at first it was clear and only a very small drop. Now its thin milky looking and still only a drop. Nauseous like no tomorrow, emotionally unhinged. 2 months ago af was VERY light and lasted normal 3 days then last af seemed more normal but lasted 2 days longer. My last pregnancy 7 years ago i bled on and off for 5 months. I keep getting bfn. Someone please help me!!
