If you are first time pill user and starting for first month, then one missed pill will be quite risky for being pregnant if you involved in unprotected sex close to your fertile or ovulation day.
Another thing, you might get withdrawal bleeding due to sudden missing of one pill. It is quite early to confirm pregnancy
I suggest you to take two pills on the very next day and continue rest of the pills as earlier. Do home pregnancy test if you miss your regular period.
Hope, it helps for you. Good luck and take care.
