implantation spotting

okay y’all! i am 6 DPO and started having some very minor cramping yesterday and some brownish/pink spotting today. i usually spot before my period but not this far before my period. i’m fairly confident this is implantation spotting, as it is similar to my last pregnancy that i ended up miscarrying.

so my question is, when should i test? i was thinking i should give it at least until Wednesday which would put me 3 days before my missed period but would be a better chance of getting a positive.

what do you guys think?
