Craving strong smells..

Is this a normal thing?

I'm 31 weeks and I haven't craved any weird foods, I'm just very addicted to eating ice at the moment. But I am craving strong smells. I was washing my face and used my noxema pads and couldnt stop sniffing it. From then on I just need a sniff of anything strong, like markers, matches, rubbing alchohol, anything.

Is this common?

Also I would like to add, I'm not huffing it. I scared my mom when I was telling her about it, and she thought I meant I was huffing it. I just need to sniff it and I'm good.
