Question

 OK y’all so I have been tracking my period and my ovulation. Last week I was ovulating, but then I started bleeding on Wednesday. It was light. It is heavier now I’m frustrated because I’m like how did I already start my period seven days early when that’s never happened before I don’t think that it’s implantation bleeding, but do you guys think it could be where maybe The sperm met the egg but didn’t attach so I’m just bleeding everything out now
