Advice needed re pregnancy and redundancy

[clareanna]

I am hoping a clever mumsnetter can help me with my situation. I am currently 14 weeks pregnant and under consultation for redundancy.
I have not told my employers that I'm pregnant as the first consultation meeting was before I was 12 weeks pg, and following a miscarriage earlier in the year, I didn't want to tell anyone this time, let alone work.
Both myself and my boss have been on holiday, so my second consultation meeting will be in 2 weeks time when I'll be 15+ weeks. It's getting more and more obvious so harder to hide.
My question is - is it better for me to tell them that I'm pg or should I just blame it on too many pies until the consultation is concluded?
I feel I am in a strong position to be kept on... there are 2 jobs and 3 people and I am well qualified for one of the jobs in particular, however am worried my pg may change that view.
NB I work for a very large organisation.
Any thoughts gratefully appreciated

I googled and came across this document which explains your rights pretty clearly.

Having said that, it depends on whether your boss is a fair person or whether he/she might use the information even though it isn't legal to do so. I guess the other factor is whether you will return to the post after your maternity leave - at the moment it sounds as if that's your intention?

tribpot thanks so much for your response. Yes, that doc is very useful - I will just bide my time for a bit, and ensure i note down any positive comments made to me during the process just in case
