How soon is too soon? 😬

Hey all!! So I have super irregular periods due to pcos (my last one was January) and for the first time since, I started spotting yesterday!!! It started out more pink-y and now is more brown, but still not even close to a period. I’ve never gotten spotting before so it made me pretty antsy. Usually when I get a period, it arrives full force!

I have also been super light headed and dizzy for a few days.

Anyone have any insight on if this were to be implantation, how long I should wait to test?

Thanks so much!!!!
