Restructuring. Lay offs. Do I tell them I'm pregnant?

[GrumpySock]

So my company has announced a limited business restructuring. They are now conducting employee consultations. Once finished they will approach individuals and announce who will have to leave.
I'm 2 months pregnant. Haven't told anyone yet. Should I tell them now or not at all? What is better?

We don't have a union.

I would. I told mine early as I was struggling physically and I had a previous miscarriage (which they knew about), so I’d rather they knew in advance. Workplaces are usually cautious if you’re pregnant!
