Vaginal Discomfort???

I ended my period like a week ago and randomly yesterday my vagina started to feel extremely uncomfortable. It feels like how it feels when you put a tampon in but it's not like fully in so it's uncomfortable and you have to adjust it?? But nothing else seems different like no smell or discharge or itchiness? and my boyfriend and i are both clean, he doesn't use condoms but pulls out and i'm on the pill and i take it regularly. i'm just super confused and it's getting really annoying.
