My friend had unprotected sex with her boyfriend he didnt pull out on time, she took the morning after pill 3 days later, but doesnt know if it...

the condom broke and i took the m.a.p  about 48 hours after sex, he did come inside me lately iv been feeling very tired, sore...

me and my boyfriend have had sex a good few times without a condom, he has always pulled out in time, could i still be pregnant ?
