Hi, thanks for using healthcare magic
It does sound like a yeast infection. A yeast infection may be associated with a white or yellow discharge and vaginal itching
but persons may not experience the symptoms the same, in your case you seem to mainly have itching.
They occur commonly in pregnancy
and can also occur after a course of antibiotics because of alteration of the normal vaginal flora
(bacteria and other organisms present).
You can consider speaking to your doctor regarding which topical ovule or cream you can use.
I hope this helps
