DON'T KNOW WHAT THIS WAS

The weirdest thing happened to me. Friday night on May 5th I woke up and went to the bathroom and there was pink on the tissue. I automatically got frustrated because I felt like my period was coming after all of our TTC. I put on a panty liner that night. That Saturday morning I woke up and urinated and there was a slight flow. Not the normal flow but I had been taking maca root drops so I was thinking that could be it. Only used 1 pad that day and really not alot of bleeding like my usual menstrual. Sunday I was back spotting, no flow, only pink when I wipe. My menstrual normally lasts 5 days and it was literally over on Sunday. This was weird because all I did after that was have pink on the tissue when I wiped. IS THIS NORMAL?????
