Vagina tingling

Hey guys I masterbated a few days ago and ever since then (literally the next morn) my vag has been slightly itchy (not sure if it’s just irritated). I’ve never had a yeast infection before so I’m not sure if it’s even that. It’s hard to describe the itchiness but it’s more of a tingle, kinda like the feeling of a bug crawling (that type of tingle). I’ve been taking probiotics and feel fine, so I genuinely don’t think it’s an infection. Do u guys have any thoughts? Why is it still slightly itchy? I’m also due for my period tomorrow, but I usually don’t get itchy a day before my period either. Anyone have any ideas?

Are yeast infections more painful itching? I don’t have thick discharge either and no burning when I pee
