PLEASE HELP ME

How it looked when I thought it was a regular cycle but just arrived late

7 days late. Negative pregnancy test and tonight I noticed light pink bleeding which I though was finally my cycle since the pregnancy test says negative again and I have also been cramping even now. Went to urine and AGAIN light pink blood. I’m soooo confused on what is really going on.

Never missed a cycle unless I was pregnant have two boys now and I NEVER had blood during the process. Can someone please give me advice. I do go back to obgyn Friday if a regular cycle doesn’t come on by then
