Phantom smells??

I’ve been doing some research, and I read that when you’re pregnant it is possible to have something called “phantom smells”. It’s where you smell something that isn’t there, and only you smell it. I once read an article and it said something about an angel trying to talk to you, and then I read on a baby website that it is a thing you experience during pregnancy. I’m just wondering if anyone has ever experienced this, or is it not normal? I just hope everything is okay with my little man, or if I should contact my OB. Thank you lol. I am a FTM, so I’m kind of worried. But at least the scent I’ve been smelling was flower petals lol. But please comment if this is normal or if I should worry.
