Hello- I am expected to get my period next Wednesday 5/13. Yesterday when I went to the bathroom one of 10 times yesterday, I noticed a very light color brown when wiping. I am not sure if this is a start of my period as this kind of happened last month too a week before. I do have tender breasts, and left pelvic pain now. Again all could be signs of either period or pregnancy. Should I be worried about this spotting though?
