I used to be regular, then I missed my period for several months, not pregnant though. Just this past week however my
period came as dark
brown throughout the whole thing, never getting red blood. my periods have been irregular and never a normal flow since feb. 2010. my boyfriend and i do have unprotected sex and only use my pills as contraceptives, which i take same time every day...been tested for stds a few months ago, what should i be concerned about???
