So my period is due today. And yesterday I had random very very light pink spotting. Today this color. I’m wondering what this is because my period is very regular & I never have spotting before my period my period literally just starts heavy and stays that way until the end. I did get a positive OPK this cycle on the 23rd or April then right back to negative on the 24th I feel like this is too late in the month to be implantation bleeding.
