Morning sickness....?

I thought I was lucky in avoiding the nausea but BAM just washed my hair and the smell of the conditioner (which I’ve used a million times!) smelt so repulsive to me and I was sick 😂🤢 how weird!!

Is it actually quite rare to not get any sickness? I was hoping I’d be a lucky one 😩 I’m worried about how to manage it at work because I’m a mental health nurse and I can’t just run off to vom during a session with a patient 🤦🏼‍♀️😂
