Hey folks. I starting spotting yesterday, a very small amount a light pink color when I wiped. I almost couldn't notice it. Today I have this. I never spot and my period isn't due for another week? Could this be implantation bleeding?! It's more brown than red. When should I test? Should I wait until my period is due or test sooner?
