Well hello there, we understand your state at present and your concern towards your health. As you ink mentioned that you have taken three oc pills and you did not.mention whether you had intercourse or not. But then taking three doses of.oc pills at not advisable without doctors prescription. You could done one pregnancy test before you taking those pills anyhow now what's done is done if there is nothing happening with you that's well and good but if you feel any unusual things happening then you need to consult a gynecologist. Thank you
