could you be feeling these symptoms already?

Ok so if I'm pregnant I'll be 3 weeks and 2 days. I've been sleeping so much, more hungry every second and crying easily now. Yesterday last night I accidentally threw up on my bfs sheet and blanket. So his grandma was in the living room with the uncle. I asked her do you got another sheet and she asked why. I told her I accidentally threw up. Then out of no where his uncle started saying "you couldn't make it to the fucking trashcan." I said it just came up and he said "that's fucking ridiculous that's fucking ridiculous." So I just went back to the room and busted out crying out of no where. I will usually be saying fuck you in my head but instead I cried.
