Help Please

Today I felt uncomfortable with my genital area but didnt think anything of it. Well about an hour ago I went the restroom and noticed I have this large lump cyst like thing immediately to the right of my clitoris.

Any ideas on what this is or what it could be??

I am panicking right now because like an idiot I tried googling it. Currently my doctor's office is closed but I am making an appointment as soon as they open and as soon as I can get in.

This has never happened before and the only romantic partner I've had in the last 4ish years has been my fiancè. (We got engaged in October).

Please help give some light to this situation as I am currently not in bed with him and panicking in my living room.

Thank you...
