Early Af or heavy implantation bleeding??

Capri

I started my AF 3 days early 7/26 (11dpo) and lasted7/29. My cycles are very regular 27-29 days with 5-7 day flow. So when I logged the 3 days my chart said ovulation a day after the bleeding stopped and I should expect another AF on the 4th which is today. Have anyone every experience this before??
