Smelling things that aren’t there?

Kay

Im 8+3 and I’m having olfactory hallucinations. I read only 14% of pregnant women have them. But I smell things, actually one particular and horrible smell, that is not there. Happened with my first pregnancy too. I’m miserable. I can’t escape it and no one else can smell it which makes me feel absolutely insane. Just wanted to know if anyone else can relate. Or have any remedies I haven’t tried (vicks under the nose is the only thing that’s helped)
