Birth control

I don't start my "period" till the 5-7 day of placebo pills. 

Just wait out the 7 days! When I first started my pills the doc said "don't be surprised if you get no period at all or a very light one" I mean I did get a withdrawal bleed and it lasted normally for about 5 days aha. But for some people they really don't get one , think about it your body's hormones have just been chucked about! It's gonna take a while to settle ahaha. My bleed comes either on the third day or the fourth day, wait it out or wait the 7 days and then start the next pack. If you're still worried then go to the doctors and ask for a new brand or give it a few months :)

Mine doesn't start until halfway through the 4th day of not taking it (I don't have placebos). It's different for everyone so just finish the pack then start a new one :)
