Job dilemma

Ok so I’m pregnant 6w5d with my second child. I have a MS in education. I used to work at a preschool for 4 years about 3 years ago I left though to pursue some other opportunities. I was 25 when I left after spending me early twenties there.

Recently I’ve fallen on some tough times and wanted to work there once more so I reached out. The principal said her and the director were skeptical about my return ( mind you I left on good terms !)

She asked why I would want to work there with my degree (in education ... mind you it’s a school !) then she made a comment like ok well you can’t just up and leave in two months. (Again last time I worked here for FOUR years) then she said ok you have to at least promise a year.

So question now, would you continue to pursue this job ? Remember I’m pregnant and in a tight situation and this is a definite job but I’m worried how they’re going to treat me once they know I’m pregnant... should I tell them up front ? Should I wait and have them be mad ? I really don’t know...

I was excited to work there and now I just don’t know :/
