possible miscarriage?

Rebekah • Mama to four beautiful babies 🧡
On march 12th I took a clear blue test, it said Pregnant!!! I was 10dpo! 
Today march 22 I have some very light brown stuff when I wipe, it hasn't got darker and hasn't got heavier. I also took a regular test and it was darker then my other test last week. Could it be the start of a miscarriage?
