If i missed a few birthcontrol pills but took them late and had sex last night is it possible for me to get pregnant.?

Yes, it's possible.: It's possible to get pregnant on birth control pills even if you take them perfectly - 100% of the time! be sure to use a back-up method (condom). If you are having trouble taking your pills regularly, you might feel more protected with a method such as an iud: no pill taking required! your local planned parenthood or health department family planning clinic can help, as can your doctor.
