Pregnant?

Desire
Okay so i dont do this like at all but i'm really stressing out. So this past month ive had to take not one but two emergency contraceptives and after both of them i bled like a period and i had my period a week before taking the first one and im actually due yesterday on christmas for my actually period but friday night i had sex with my boyfriend and the condom broke and we decided not to take the plan b again because its been making me extremly sick. I just want to know if i could get pregnant when originally my period is due yesterday or if my period will be off due to the plan b's i had taken and then bleeding like a period after them both. This is all confusing because now my cycle is all messed up from the plan b's.
