Implantation or just my PCOS?? PLEASE HELP!!

Curties

Hello so I bled light pink this morning and by this evening nothing was there… and tonight.. still isn’t. Has this happened to anyone? And could this be implantation? *ALL OF GHIS ONLY HAPPENS WHEN I WIPE. So not enough to fill a pad or liner*

Btw… same thing happened last week.

2/10-light pink next TWO days NOTHING.

2/13-VERY light pink NEXT day NOTHING.

2/15- VERY link pink next 7 days NOTHING.

TODAY- Light pink…. By tonight NOTHING.

Does implantation bleeding only happen 3 days one time or what? I’m going to test soon… BTW my last period ended FEBRUARY 2nd!!
