Hello; first time posting, have a small question, how many days after implantation bleeding should I wait to test? Today is the second day after I was done spotting dark brown and it was negative, is it too soon? Thanks in advance

Would like to add Glow calculates my period in the next 3 days but Ive been super irregular my whole life to the point ive gone almost a year with no periods and but recently been having them very often sometimes twice a month
