Pregnant and daycare?

I'm about to work at a daycare and my husband and I are tcc. I was wondering if anyone has or is working in daycare and how they treat you while your pregnant? I've worked in daycare before it's not a good place to work but have to pay the bills. Also I'm afraid that when I do get pregnant when I go on maternity leave will I have a job to go back to? Do most daycare give a discount on daycare service while you work there? Thanks!
