It’s not going well :(

Hi there, I just found out that I’m preggy and about 5 weeks 4 days. However I just started my new job this month and the workload is crazy and it’s going super fast pace which previously I’m ok as I’m use to it but..I’m currently experiencing bad bad changes in my body such like having a dry cough very bad dry cough, vomiting but nothing to vomit. Extreme tired. Should I let my current employers know or should I just quit and focus on the health? :(
