Heavy implantation bleeding.

Kalie
I know it's supposed to be light but I have read a few women where it was heavy and went on to have healthy babies. 7dpo and started my Period which is very unlike me. I have never been early. I was wondering if it was implantation but felt discouraged because it was heavy but it only lasted a day and a half and is now spotting and brown. Anyone else experienced this? I feel crazy but I could bet my life savings in my period so this is weird for it to be a week early. 2nd miscarriage Sept 12 but my period went right back to normal the following month like nothing had happened. I bd every day a week before my fertile window and after so I know the timing was fine.
