Does this sound like a yeast infection?

Kinda TMI... I just gave birth 3 weeks ago and about a week ago I noticed I started itching down there really bad. No discharge. No smell. Just really itchy dry and irritated. I went to the doctor right away and she gave me 2 doses of diflucan. I took it but I’m still itchy and irritated down there. I read that it can take up to 7 days to go away but it’s been 7 days now and nothing.

Anyone gone through this before? Does it sound like a yeast infection?
