Hi, 6 Days Ago I Took Levonelle, 3 Days Ago

hi, 6 days ago i took levonelle, 3 days ago i got a sore throat and 2 days ago i developed a rash starting from my chest and spreaded all over my body, my face also swelled up. im not sure if this is due to the pill or not due to the huge time gap. if it is, the sore throat has decreased and my face is not swollen anymore... how long will it take for the rash to go?!
