Morning sickness and the inevitable...

I HATE morning sickness 😭 more like all day sickness but whatever lol.

Im an IOP therapist, doing about 2 groups a day. I'm in my first trimester, but I'm hoping to keep my pregnancy private as long as possible in the workplace. I've worked out ways to prevent getting nauseous in the first place, but none of us are perfect and I'm anticipating the likely eventuality of needing to excuse myself abruptly. Where I work, I have a coworker with me, but she's not always in the group room with me (handling other tasks she has, etc). I legally/ethically can't leave the clients alone. So, in the event I am the only clinician present and I start feeling rumbles... What's your advice? Just go for the trash can and explain later? Pretend nothing happened? Idk 😐
