I have faint blood dots on the tissue when I wiped, and lumps on my areola's, I also have pcos, could I be pregnant?

Pregnancy. There is no way to know if you are pregnant based on the color, character or amount of vaginal bleeding. Also, many signs/symptoms of pregnancy may be signs/symptoms of other cycle related issues. With pcos, you may not have regular, predictable cycles that allow for knowledge of predicted ovulation. If you've had unprotected sex and could have possibly ovulated, check a pregnancy test.
