Help!!

I've been feeling super off today. Cant keep fluids down bc it makes me sick. I'm a CNA in a long term care facility and I noticed my ankles were swollen after work also after I got home I've felt super nauseous and dizzy and having some cramps mid belly on my right side and I've been feeling like it's hard to get a good breath. I'm 11 weeks pregnant and I have a dr app in late afternoon tomorrow but what could be going on ?
