Could I be pregnant?

So I had sex with two guys and both were unprotected but the second guy bought me a plan b pill when I was ovulating it said on my apps then I got my period 2 days later it only lasted 3/4 days and now I’ve been extremely nauseous, peeing all the time, and craving stuff I usually don’t have and haven’t sex since the time he bought me the plan b which was January 17th. I don’t think I am, but just opinions lol.
