I’m confused

So I took a plan B recently maybe a week or two ago bc I had an accident with the entire condom breaking and he came in me 100%.. so my period started early but it was only two days.. so after that I’m fine I guess I’m like ok well two days fine. It’s now been another week or maybe a few days and my boobs hurt.. I’m getting ready to ovulate soon but not for another 7 days or so and I’m already having sore breast?? I’m also nauseous, bloating and I’m cramping and I don’t cramp on my period and I’m nowhere near my period like what is going on? Any clue? I’m having pregnancy or pms symptoms and I’m nowhere near either one
