Af due 3/22 .... Light spotting.

Had light spotting today when wiping. Never spotted this early before AF is due. Usually a day before if that. 9 days past possible ovulation. Could be implantation bleeding ? New to <a href="https://play.google.com/store/apps/details?id=com.glow.android">tracking ovulation</a> and implantation. So it shocked me to see blood.
