text: You can skip them but If your pills change dose weekly (ex. OTC-lo) you may end up bleeding for a month, or if your lucky just have some spotting. Other pills dont change doses are best for it but still can have spotting. A doctor put my friend who had real bad period problems on the pill 24/7 no more periods ever, but did get unpredictable spotting. The doctor said that it was healthy.  There is going to be a pill on the market soon out that lets you have only once a year. But break-though bleeding is evil and just a bad as a period and with pills that let you skip your period that happens more often then on the reg. pills.
