What kind of 3-15 second periods of sleep occurs during normal waking activity?

No, it's not normal. You should go to the doctor, you may need to get a new kind of pill. Answer And you should use a back up method of birth control in the meantime. You pill may not be working and you could get pregnant. Answer Just went to doctor today and asked very same question. She said that it is not uncommon. She said your system will eventually adjust and there should be nothing to worry about. I asked her if my chances of getting pregnant are higher when this happens. She said no that as long as I take pills every day at or around same time, I am 99% protected regardless and don't need another form of birth control as a backup.
