Shaving

What’s the best and most effective way to shave your vagina? I use regular dove soap and dove for sensitive skin when shaving my vagina but recently I’ve been experiencing a little itching and burning in my vagina and I’m not sure if it’s because of the soap I’m using to shave or what. Should I switch to using unscented dove or what? I plan on making a appointment to see a obgyn for a pelvic exam next week.
