Vaginal Irritation

Je
Is anyone else experiencing vaginal irritation/pain? I noticed it the day after my first vaginal ultrasound (this past Sunday) and it's been a constant small irritation anytime I wipe. Almost like an yeast or an uti infection about to happen but it hasn't gotten worse. I'm afraid to have sex because it just seems raw and I'm afraid it'll hurt. Anyone else? Not sure what to do for this right now...
