Help! Im starting a new job and 17 weeks pregnant. The boss does NOT know

Hi, I was layed off in October 2018 and a week later I got pregnant! So so so happy!! So now im 17 weeks (showing a little) and starting a job this week and I deliberately didn’t tell them that I am pregnant. I have been looking for a job since October and I wanted to take the high road and be honest while looking for work. I don’t know how many times I was refused because they are looking for a longterm commitment as an employee. Im planning on tacking a maternity leave for a year.

So coming back to my delima... i HATE HATE HATE to be dishonest about my pregnancy and im such a proud mama to be.. breaks my heart to hide it. I honestly do not know how ill tell my boss and coworkers that I am. How it will affect my work environment. Im mad, confused and disappointed that I can’t openly tell people that im pregnant. How do I approche it?

I need to work to come up with 600 hours to get unemployment (a service that will allow me to get maternal unemployment service which helps me pay the bills)
