Implantation Bleeding???

Sooo I am almost exactly 28 days every month. Been off the pill for 8 months and TTC for 3 months. 9DPO I had light dark spotting and low light cramps. The next day I had light pink spotting and no cramps. 11DPO and 4 days before my normal start I started medium red bleeding and cramps. I'm never early. Now I'm confused and heart broken Bc I think I had implantation and now something is wrong. Anyone have this happen??
