Uhhh..
No. Virtually everything you have researched is wrong.
It is far more likely it is the result of either a piece of unshed skin in her nostrils or the start of a respitory infection from adding an unquarantined animal to her enclosure.
I know it is unquarantined as any decent QT procedures last longer than your male has been alive.
They do not make any noises as a result of breeding.
I'll bet you dollars to donuts your interpreting territorial competition and stress as " getting along famously"
And, since you ignored the "one animal one enclosure" recommendations, if it is an RI then you will probably have to take both to the vets.
