8 weeks pregnant.. should I tell my potential employer?..

Would it be bad of me to interview for a new job without telling them I’m pregnant?

My current job is working with people with mental health and/or learning disabilities where I am sometimes subject to behaviours and can end up in restraints. When we started ttc I applied for some low risk jobs, I applied for a receptionist position just before I found out I was pregnant at the end of November. Since then I’ve found out I’m pregnant and didn’t think anything of the job as I hadn’t heard from them.. but they rang me today to offer me an interview next week. I’m buzzing but I’m also in two minds if to tell them I’m pregnant. I wouldn’t want to lie and I know they’re not supposed to discriminate but I know it’ll go against me if they think I’ll be leaving again in 6 months for maternity leave.

Help 😅
