You are using charge in some non-standard way. Charges are source or sinks of the field.
An electromagnetic field does not sink or source more field- if it did, Maxwell’s equations would be non-linear. There is no such thing as a ‘negatively charged electromagnetic field’- there are just electromagnetic fields. Now, the electromagnetic field can have a negative (or positive) amplitude but this is not the same as saying its negatively charged.
