Implantation bleeding or period!

Elles Belles

I am sooo frustrated!!! I track properly and have done so for the past 2 years. I am 8dpo and yesterday and today have had light bleeding. I think too much for what I've read about implantation bleeding so it's like light period. Also have cramps and backache like af. I feel like it's a period but ive never had period this early. I've never really understood the 2ww problem until now.
