anyone been through this?

Choc • 9/11/18
So my period is "18 days" late though and the week before I was supposed to start I had two separate days one day apart when I went to the bathroom and wiped and it was light blood but nothing else for the rest of the day. I've had two negative prego test. I was on nexplanon until oct. So now I'm thinking maybe my body is just adjusting but idk..
