TMI: Period or Implantation Bleeding?

Kristine

Hi. Sorry for TMI. I was estimated to have my period last April 25, but it’s late. However, due to anxiety, I decided to take hpt on April 30, but it is negative. Yesterday, May 1, after dinner, I see blood already in my panty (first pic); Second picture was taken earlier today, May 2, i used a pantyliner. Am I only having a light period? I also found some small blood clots in toilet and tissue (taken recently).
