moving from temporary contract to permanent - what do I need to know for planning pregnancy?

[ThePartyArtist]

I'm currently on a short term contract until Sept 2016, after which I've been told by my manager it'll become permanent. I'll get to sign the permanent contract around June 2016. I'm hoping to TTC soon. What do I need to bear in mind re: maternity leave? If I announced pregnancy during the temporary contract would I potentially have the permanent contract taken away from me (I won't be able to sign it for another 10 months)? Does it make any difference if I begin Mat leave during the temp contract rather than the permanent one? I have continuous service so don't think it would, but obviously it's hard to ask HR!

Pregnancy isn't meant to make a difference, but it would be naive to think no woman on a temp contract has ever been denied permanent status due to being up the duff. In your shoes, unless time was of the essence I'd probably wait six months before TTC.
