How do I support my wife? Ethical question

I'm emetophobic. So is my wife, but not quite as bad. She's pregnant with our first kid, and she has sb* right now (it's definitely not just morning sickness). I'm caught between wanting to help my amazing pregnant wife and being terrified to go near her. My strategy so far has been to give her everything I can while keeping her quarantined in the bedroom/bathroom while I sleep on the couch. She knows how emetophobic I am and she's expressed that she's okay with this, but simultaneously it's clear she wants some physical contact too. It's been about 24 hours of this, and she last v* about 12 hours ago, but hasn't showered or anything. Should I just suck it up and go be with her, accepting the increased odds of getting it myself? Or is it okay to insist we keep our distance for a few days?

Honest opinions are welcome. Let me know if I'm in the wrong.
