i see my reputation preceeds me... dunno good or bad leh..
hahaha
well so u did take rite? and did u menstruate? u were saying a lot,
then a little then alot?
well first problem, if it's really MENSTRUATION (and not some
vaginal bleeding due to other reasons) then u're definitely not
pregnant. so that's the good news. how to tell if it's menstrual
blood? i'm sure u'll have a better ans then me, i am, after all,
not a girl! 
anyway if it's alot of blood, i dun think it's abnormal vaginal
bleeding. but anyway if ur irregular flow is out of the ordinary
and prolonged, see a doc, that one i have no idea.
take care~
