Vaginal opening itchiness!!

I know this is TMI but I have had this for over a month and it’s driving me crazy. It’s worse at night and is right at the opening of the vagina. My obgyn gave me fluconazole for yeast infection over the phone because they wouldn’t let me come in due to coronavirus. It obviously didn’t make the problem better. Sex is uncomfortable. I can’t sleep at night and I accidentally scratch myself!! I do not have any stds as I have been tested and have only been with my boyfriend since we’ve been together. I’m still breastfeeding part time so I can’t just take anything. But I need this gone!! Anyone have any remedies or ideas of what this sounds like?
