Hi. I Had Unprotected Sex On 3rd Dec And Took

Hi. I had unprotected sex on 3rd dec and took ipill within 6-8 hrs. N den again we had unprotected sex next day and took ipill in 30 hrs. I recently got cured from cyst in right ovary. After 7 days of ipill intake i had my period which was light at first n den like my normal periods with clotting. This period occured a week earlier then my expected date. Are there any chances of pregnancy after getting one period?
