First morning sickness 😩

Linda • 23, married, 3rd pregnancy, but first baby that stuck 😊🌈🎀
So, I'm 11w3d pregnant, and have felt fine these entire 11 weeks, except for loss of appetite. This morning, while getting ready for work, of all things, I was BRUSHING MY TEETH! and it made me throw up. I called off work because now I have vomit breath, and I can't even brush my teeth to get rid of it. The smell of gum makes me nauseous, and I don't even want to THINK about mouth wash. Either way, Friday is my last day at work, so only 3 days left. I CANT WAIT! Now I'm just sitting here trying to figure out how to get rid of the acidity in my throat 😶
What was your very first trigger for morning sickness?
