Itchy

I’m pregnant 23 weeks n I’m super itchy down there got tested at hospital but it’s not any std supposedly or yeast infection don’t know what it is but I have to wait until Thursday to get seen by my Ob. I tried to make an earlier appointment but they said no they don’t have any. I’m legit dying over here I’m sooo itchyyyyyy 😭 is there anything I can do to relieve it.
