Assuming you topped your oil up when the engine was hot, give it to the morning to fully cool then check it and top it up again and go from there.
No such thing as a silly question, especially when it comes to your engine oil level.
I know of someone that had their brand new Audi S5 oil topped up by a young buck in Halfords (Don't know why they went there). Topped it right up to the oil cap, a new £7k engine later and one sacked employee and the car was running great!
