I always take my birth control at 9pm. Several days ago I completely forgot to take it and took it at 9pm the next night as usual. It took until the next night for me to realize that I had skipped an entire day, but I took the extra pill and I've been continuing to take it at 9 every night since then. I checked my birth control pamphlet but couldn't find anything specific about going 24 hours between pills. Do I need to worry?
