Pink Spotting days after AF?

Has anyone had something similar happen to them? I had a short period, it was 4 days usually 7, and then completely ended. 5 days later the whole day, every time I used the restroom there was pink spotting on the tp and I had light discomfort in my lower abdomen area? I can’t catch a break now I’m feeling a cold coming on with a stuffy nose:(

*I took a test 2 days after spotting and it was negative
