So my period comes every 5 weeks. I'm 13 DPO and my period is not due for another week. I've been cramping since 6 DPO and 11 DPO (two days ago) I had pink (and I mean PINK) blood. So I assumed it was implantation bleeding since it was pink and I've been experiencing cramping. Then yesterday it stopped. But just today I started spotting again and now it's brown and light red, just like my period starting.
