They cant deny you employment based on the fact that youre pregnant. Dont hide it, if they do hire you they are going to know either way. Just do your best at the interview. My friend was hired at a job two weeks before her due date
My advice would be just be honest they cannot discriminate against you due to pregnancy but he can fire you for lying about the pregnancy plus it's not like you can hide it long lol
Good luck, generally they wont ask you if your expecting, and not telling them isnt lieing about being pregnant, You can initiate it and inform them that your expecting but my advice is do what you need to do to get the job if your really in need of it. As long as your able to perform the duties your applying for.
