Girls, hello! Who has been having their upper teeth out for how long?

Girls, hello! Who has been having their upper teeth out for how long? And at what time did you come out? It all started a month ago with tears not coming out for a minute, capricious and terrible. A couple of weeks ago we got sick and the pediatrician says the upper gum is very swollen and wait for the teeth. The last three days it's not from one thing to another that the child's temperature rises to 38.8. Easy to knock down but only for 5 hours maximum. Now I called the pediatrician to exclude infection or vice versa. So, how long will this last? As I remember, the older sister had only problems with the lower first ones and all others came out by light.
