My colleagues and boss is not giving me support

Currently in my 3rd trimester and feeling very very tired, had my vaccination for whooping cough and got a fever , took unpaid leave , but boss and colleague is not happy about it , I’m very stressful at my work place , hv to see ppl face to take leave / MC / HL whenever I’m not well , I really just counting down for my maternity and I just want to get out of my workplace fast. It’s making me stressful and unhappy for the whole of my pregnancy.
