This is sort of embarring...?

But, the last two days my vagina has been itching badly, on the inside. Now, I haven't been ually active in a month and I was taking Amoxicillin the other day getting over tonsillitis. So could it be a side affect from that? I haven't switched shower soap lately, orr laundry soap..and I still take a shower every day so I'm not sure.
