4 days late BFN

M

Usually I have normal periods about 7 days long. But in November I had a period only for 4 short days. December I didn't get a period until the 30th to January 2nd, 4 days again. January 5th I started spotting only that day tho. Three days later on the 8th-11th I was bleeding light to medium. my app says I'm 4 days late but I'm not sure if it's counting the couple days i randomly bled. I've taken 2 tests and both BFN. I've been nauseous, dizzy, headaches, and had tender breasts. I also have a orange/yellow discharge or milk coming out my left nipple and clear discharge on my right nipple both only when squeezed. please please help
