Hi Doctor! So My Boyfriend And I Had Sex Using

Hi doctor! So my boyfriend and i had sex using a condom but unfortunately the condom broke we're not sure if he ejaculated inside me because we can see some of the fluids outside my vagina and after 2 hrs i took nordette as ecp 4pills and another 4 after 12 hrs. We had sex last october 29 and my period ended just october 27 will i get pregnant? How effective is nordette as ecp?
