Implantation or early period?

Rebecca

Hi everyone! I began spotting on May 13th and have been since. I ovulated on the 12th. Do you think this spotting is due to ovulation, implantation, or an early period? My period is due to start in 5 days. 🤷🏼‍♀️ When I found out I was pregnant last time it was one wipe of light pink, I took a pregnancy test and I was pregnant. So this time has me really confused.
