Is this Implantation or Period

Tiarra

Hi Ladies need some help!

My period was due on the 23rd of this month. Ovulation day was on the 11th. This app has been spot on for everything for me. On the 23rd I started spotting and it was pinkish. I don't have my normal cramps or feel heavy like I normally do when I get my menstrual cycle. But anyways the spotting lasted for 23rd and 24th as of today is was brown and has completely stopped. Confused I'm not sure if this is my period or not.
