Possible IB when to test?

6 dpo was the 5th of June I only had a tinge of pink when I wiped once in the morning June 6th I was spotting pink mixed with cm throughout the whole day and now on the 7th it’s more brown and very light also mixed with cm and its almost completely stopped by today so my question is how long should I wait to test ? Do you think I could test tomorrow and get a positive? This is my rainbow and I’ve been trying for a year one miscarriage last year in June please let me know what y’all think💕
