Ghusl after a wet dream for a woman

I asked you a question regarding wet dreams that to what extent should I check the discharge, after awakening after having a wet dream. Should I check with a tissue or with my hand inside the lips because there was sometimes discharge of a very small quantity which was only inside and not visible outside. You replied that if there is no discharge on the surface then you don't need to check further.

I just want to confirm that you mean the visible surface here? It means the outer genetalia which is apparent while the lips are normally closed. If dischrage does not come out or visible to that area, ghusl is not fard on me? Even if its inside?
