Missed one pill

Kira

I missed one pill this week. I usually take them at night but i took it in the morning because i was out at night.

I started taking them on time right after that day but i had unprotected sex two days after my missed pill. Of course for those two days i took them on time, is there a possibility of getting pregnant?

Should i take an emergency contraceptive? Would that effect the birth control pill I'm on now?

Help!!
