Steroid creams thin the skin so I am very sceptical about using steroids on our intimate area as it could make things worse. As others have said, steroid creams don't really help generally unless you are diagnosed with a skin condition that actually requires steroids and even then it should only be used for a short time.
I would stop this steroid till you have seen the specialist and had a proper diagnosis.
If the coconut oil helped then this is a good natural
Moisturiser. The Vagifem can take up to 3 months to really restore things and again, as others have said, sometimes systemic HRT is needed alongside the local oestrogen to really help if your problem is urogenital atrophy.
Try holding a bag of frozen peas wrapped in a tea towel onto the area to relieve the itch and burning feeling. You could also try some lidocaine cream that may reduce the inflammation and pain - I think you can buy this at the chemist but you can get this online.
I do sympathise, any discomfort around our intimate area is very distressing. DG x.
