Should I stop using Broncho-Vaxom If I started therapy 3 days too early by mistake?

Hello, my son of 8 years old started the 3rd series of broncho vaxon by mistake, he got the tablet in 17 days instead of after a 20 day break. He has already taken 3 doses, should I take a 3 day break or continue to give more doses. And whether it's a coincidence or some kind of allergic reaction that with each series he has a severe runny nose, once a stuffy nose, once a runny nose, in the meantime he caught an ear infection and is already on the 2nd antibiotic, Amotaks did not help, now he is treated with Klacid.
