Taking a break from work?

Hello everyone, i’m a first time mum working as a customer service officer. Due to the stress of my job and how i’m not coping well physically in the first tri, i have thought on taking a break from work. I’ve used up all my MCs as well. I’m just wondering if i do quit and rest will there be a company who will hire pregnant mum’s? Or will the chance be slim? I’m so stressed thinking abt this cos i feel like my manager doesn’t understand. I hope some of you can help me out with my concern. #pleasehelp #firsttimemom #worried
