Itchy vag

I've had an itchy vag for weeks now, but I doubt it's a yeast infection on account of the lack of discharge and no funky smell. It only comes about after I shower but otherwise, it's never itchy. Is this just a weird pregnancy symptom? Im using the same soap I always have, Dove, haven't even changed the kind I use, it's always the regular one with blue packaging. I keep forgetting to ask my doctor since it's not a constant itch but it's annoying, I don't want to deal with it while I'm in labor. Any ideas? And no, it's not an std lol
