Confused!!

Ashley • Love my son! Ttc baby #2. Blocked Fallopian tubes 🙁 surgery is May 21st ❤️

I had a regular period aug2-aug 6th. But this morning I had some light pink spotting ( has stopped) and found that odd so I took a test and it was POSITIVE. How ? What? I am cycle day 10! How is this positive? I also took a test the day before my period was due aug 1st and it was negative!!
