So about 4 days ago (10 days before my period is due) I started having sore boobs and light spotting which was brown. I don’t ever have sore boobs even on my period. So I was thinking maybe this is implantation bleeding. But it hasn’t stopped and it was still brown. Until this morning when I started having some cramps and I noticed red blood when I went to the bathroom. Not a lot but a little more than I have had. My boobs are still tender. Not due for my period for another 6 days. What is going on??
