Face masks

I’ve never been one to complain about my face mask i wear the disposable ones they’re easier for me to breathe in I’m 8 weeks and i can not for the life of me be at work for longer then an hour bc i can’t stop throwing up. I only usually throw up about once at home I’ve only worked a couple days since getting morning sickness but i 100% believe it’s the mask making me so sick idk maybe not enough airflow not sure. Does anyone else have this issue or have any tips to make this less horrible. I tried a face shield which still makes me sick and the gator masks wearing it around my neck makes me feel yucky. I feel bad at work I’m practically useless :(
