Any teachers battling morning sickness?

Meg • 🍍
Hey ladies! I'm curious - any teachers out here? This is my first pregnancy and today morning sickness hit me badly this morning. Luckily no vomiting but nausea like crazy!
How do we handle this as teachers? I'm terrified what will happen if I have to get sick and there's no one to cover my class! Worse yet, there are only two staff bathrooms in the whole building!
Any advice on how to cope?
