Can you get pregnant if you have a IUD and birth control pill?

If you're asking is it physically possible, then the answer would be yes. But in reality, no, it's not. The Birth Control pill is 99% effective (if used correctly) and using another form of birth control can seriously mess up your health. Your hormone levels would be way off. This can affect your skin, your sleep patterns, how much you eat, the seriousness of your cramps, how heavy/often your periods are, and even the health of your bones. You're probably better off just sticking with one form of birth control and using condoms.
