so for my whole period life lol my period has been regular even with taking BC then stopping BC regular I can always count on it being there every month. however the last two months it's been weird! 5+ days late and when it did come it was real lite and spotty then one day of like red actual blood then more brown spotting. Soo should I be concerned should i test more I know ppl say stress but I honestly do not feel stressed.
