Seeking employment whilst pregnant 😕

Morning ladies.. I'm currently 11+ weeks and job hunting due to just having found out I'm being made redundant at the end of March (which will place me approx 15 weeks). My question is at what point do you think I should tell prospective employers that I'm expecting? I'm thinking be honest at interview then if they want my skills they'll take me on regardless yet in another breath who would take on a pregnant woman knowing they may potentially have to readvertise in a few months.
