HELP ME

Someone please help me out here, my boobs usually always hurt like a week before I get my period and usually it's just the sides, but this past month I started having sex again (which I haven't had in a year) and one time we didn't use a condom but idk if he came in me, we got the morning after pill but the only thing is, my period doesn't come till the end of the month, so why would my boobs hurt now? And it's like my nipples are so sore I can't even touch them..(tmi) sorry but someone help
