Advice? Jobs and pregnancy.

Hello, I just found out I'm pregnant with baby #4.

I feel so torn right now because I just got offered a dream job position today and will need to start a 6 month probation period for it... And then right after that's all done and good I'll have to give a maternity leave notice. (As you need give 8 weeks notice)

I'm terrified of losing my position during probation because of the pregnancy. I hope to keep it very hidden until June (but that's going to be very hard as I'll be 7 months pregnant by then)

Ugh, maybe just venting as it wasn't in my plans.
