Blood 🩸 (bright red) spots

San

This is my first week of TTC and today is my CD15. Is saw a bright red blood spot on toilet paper(wasn’t much) . It has never been before anything like this. My periods won’t start 7th of next month. After seeing that I was experiencing chills and weird sensation on my abdominal (May be I was overthinking) . Can anyone tell me if it was normal or I need to see a doctor.
