Itching on vulva. Irregular periods.

I have been facing intense itching on my vulva since past 4-5 days. It itches so much that I'm forced to scratch it repeatedly which results in burning sensation of skin and it becomes wet from some liquid oozing because of the scratching ( I'm thinking its because of the small cuts that happen because of scratching). I try to maintain good hygiene, and i use clean and dry foam to clean my vulva, not vagina. Today i noticed due to intense itching the vagina external lips that is the vulva has become slightly wrinkly and swollen because of the itching. This happened 2 months back as well and it took me 2 weeks to get rid of it with extreme itching. I am somehow suspecting it's yeast infection, but there is no unpleasant odour or discharge. Only intense itching. I use candid powder and this ointment eberconazole 1% at night before sleeping. Context: i am a 22 yo, and have never had sex before. I do have irregular periods.
