Job interview

I'm a nurse that works Monday through Friday and I take call about 12 days a month where I'm usually called in... (So I end up working a lot of weekends and holidays) I had been debating on whether or not to find a new job before the baby arrives...  I had applied for a part time position at a private OR a few weeks ago but later found out that they don't offer insurance.... (So I was just going to stop my job search until after the baby is born) They called me yesterday and said they added a new full time position that offers insurance. I interview tomorrow and am nervous about telling them that I'm pregnant... If I leave my current job, I would lose my short term disability which is 60% of my pay for 6 weeks and my fmla that would cover me till 12 weeks, since it's a different company. I'm not sure how the maternity leave at the new place would work and if they even offer that... I know this job would would be better with an infant at home instead of the one I have... And I'm willing to cut my maternity leave in half if thats the case... This would be a great opportunity if I wasn't pregnant... I just don't know what to do.... 😞
