Hello. My Name Is Gabby And I Am 21 Years

Hello. My name is Gabby and I am 21 years old. I weigh just over 8 stone and I am 5ft 2'' in height. I do have type one diabetes of which I have had for just over 17 years. Today whilst in the bath, I was health checking myself and when it came to my vaginal area I felt a little lump or kind of like a skin tag just below my vaginal opening. It is not painful, can't be any bigger than 2mm and is not itchy or causing any discomfort. It is the only one of which I can see. To describe the colour I'd say a pale white colour. I have had the human papilloma virus vaccine when I was about 15/16 years of age. As for my sex life, I am sexually active and I am also taking the Marvelon contraceptive pill. I am just looking for some advice as to what this 'tag' might be. The only thing I can think of is that it is scarring off a really bad yeast infection I had about 2 years ago which resulted in me suffering with constant tearing of the vaginal skin for about 18 months and was put on a hydrocortisone cream to help cure it. Thank you for any help.
