Hello. I just want to share and ask you something about my situation.

Last June I didn't have a period. And June 30 i started spotting for 2 weeks. By July 29 I got my period. And on my CD18 I started to spotting (light pink spotting). And now its been 6 days I'm still spotting. I am so paranoid right now. Do I need to test now? Or call the doctor to test me? Please help. Thank you.
