New job first time mom 😱

I could really use some opinions here. I’m currently at a job that I’m not so excited about and haven’t been for a while.

Anyway, I’m being recruited since December for a new position that means a substantial both career and salary growth. We found out we were expecting just a few weeks ago and I still haven’t been made an offer but we talked about entry date when I’ll be maybe 8-10 weeks.

I’m not sure when and if I should mention I’m pregnant and I’m a bit scared I’ll loose the opportunity if I tell them before I start but it’s probably worse if I tell them after.

What do you think I should do? All strategy ideas are welcome 🙏
