Why did you take two placebo pills? You could simply not take the placbos (that's what I do because I hate taking pills) as they are simply sugar, and do not affect your body in any way. Anyway, since you've been off the active pills for... A day, I guess? -- it is possible that this was long enough for your body to respond and begin the menstrual cycle. I have no idea if the active pills will stop it, but your body does have to get rid of whatever menstrual materal is in there.

hi,
i missed two days on my period and so i took two of the first week and one of the second. i had sex that night and started bleeding, but didn't realize till the morning after we had sex again, but i wasn't bleeding then at all. but that night i started again and now its been three days since that last time and i am still bleeding. its pretty heavy like a period. WHAT'S WRONG WITH ME?!!
