Letrozole causing itching?

My doctor has me on 5mg of letrozole and I took the last pills last night. Since yesterday, I’ve been having annoying vaginal itchiness. It feels like it’s on the inside and there’s nothing I can do about it. Just wondering if this is a normal symptom? This is the first time I’ve taken it, so I wasn’t sure what to expect. Have any of you dealt with this? How long before it went away?
