Best thing you can do is fully read through the pamphlet your bc comes with, understand how to take it, how it works, what to do in case of missed/late dose, and what can affect its effectiveness. The pamphlet also includes a list of side effects that you can expect, but there's no way of predicting of how your body will react to bc. Just keep an open mind and understand that you'll be going through an adjustment phase (up to 3-6 months) and your body needs some time to get used to it.
