I'm sorry but I find it so funny how people act like birth control fails 99% of the time... There is only a 0.1% chance of getting pregnant on birth control... Also if you are so badly trying not to get pregnant you can help prevent pregnancy by adding other contraceptives to birth control by using spermicide(acts like a lube but kills the sperm) and wearing a female or male condom as well! The chances of you getting pregnant will be pretty much null and void....
