Please help! TMI Thrush vs BV?!!

This is really embarrassing for me but I think I might have BV or thrush but I don’t know which and I don’t know what to do.

I have itching down there particularly round the entrance to my vagina. It’s very uncomfortable, sore and there is now a little bit of swelling I think. There is no smell or changes to discharge (although I have been using sudocream the last 48 hrs to try and help so now I’m worried I wouldn’t even know if there are changes to my discharge because I just see reminants of sudocream)

I went online and thought I might have BV so went to the supermarket and bought some Vagisil cream and a BV pessisary treatment. The cream has helped a bit but I’ve just put in the pessisary before bed like it said to and it feels like it’s stinging a little bit and I didn’t have any stinging before so I have done even more searching and the website for the brand of treatment I bought says my symptoms match up with Thrush more than BV so now I’m worried that this pessisary is going to make it worse. I don’t know what to do and any advice or suggestions would be really appreciated. Thank you.
