Swollen tonsils with white pus sacks?

well im 14 now and i had strep throat wen i was 12. the test came back negative, but the doctor was almost positive it was strep throat. so i think u should take her to the pediatrician and not hav her go to skool becuz its contagious. o and my symptoms were swollen tonsels and puss sacks as well as ur daughter so she probably has strep throat but im no doctor soo u should take her in to the doctors
