Some modern music is atonal, where it lacks a specific tonal center, and as such doesn't fit into any regular key. It's easier to write in accidentals as needed rather than try to use a key signature with any flats or sharps.

No, you typically do not put a period after your signature in formal documents or emails. A signature is considered a standalone element, and adding a period can be seen as unnecessary punctuation. However, in informal contexts, personal preference may allow for some flexibility.
If you havent had your period in 7 months you probably need to go to the doctor, that is not normal.
If you have not ever in your life had a period then no but if you have had your period before then yes it is VERY possible
