ITCHY VAGINA

This isn’t really to do with a period but it’s about down there. Ok so my vagina is itchy. Like, not REALLY itchy but just uncomfy. Today i had thick white discharge but after i showered I’ve had nothing. I used nair (sensitive) to remove all my hair down there last night (i’ve done it before and had no problems) and when I examined my vagina there were no lumps, bumps, swelling or anything. I’m also on the combined pill and i have a boyfriend, we use no protection, however we’re each other’s first without anything. Why is it itchy? I’ve had a yeast infection before but this isn’t anything as bad as that. HELP!
