could i be pregnant?

so like two weeks ago my boyfriend and i were having sex and his condom ripped and he hadn’t came yet but we went to go buy plan b and i took it. i haven’t experienced any morning sickness thus far or anything else but i did experience swollen and tender breasts for a few days. the pain went away but my boobs are still a little swollen. also, i can’t recall if i was ovulating or not. any help or advice?? thank you in advance!
