Of course. You absolutely can get pregnant from that.
The pill is only fully effective if you take it every day. That's why they tell you to take it every day, not once a week, not once a month, not any other time frame. Every day and at the same time every day.
Women can get pregnant even if they just miss a day or two of taking the pill. So sometimes it takes longer for a woman to get pregnant after coming off the pill, then other times the woman gets pregnant after just a few days.
If you do not want to get pregnant, you have to use birth control every single time.
All you can do now is see if you miss your next period and take a pregnancy test.
