my story is a bit different...

i had to have a cervical stitch removed and had a good chance of going into labour within 48 hours so we only told our mums, and my belly buddies , that i was going in to have it done.
As it turned out i didnt go into labour and was induced a few days later, again no one knew.
we had a rough trot getting our DD so didnt want to be harassed in the last few weeks about whether she had arrived etc
