Im a virgin but I have a question about penetration

Okay so I don’t have sex with anyone but I do have a vibrator thing. Every time I’m close to my period, I seem to be hornier than normal and want to use it. So I do and then that night or the next day, I’ll get my period. Could this all be a coincidence or can the penetration from the vibrator thing encourage my period to come? I was three days late actually and it finally showed up after masturbating last night
