Hello, I am currently on paraguard IUD and have been for the last 7 months. Each month has been a very heavy period (which I was warned about) but this month I've had light pink spotting, noticed on two different bathroom trips 2 days apart. It has been 5 days, and still no full on period. My breast are very sore and before the spotting, the left breast was swollen. What could be going on? Am I pregnant? I (got a negative test) is it just crazy hormones? Thanks!
