Hmmm... I didn't quite understand if you are working at present or not and when the "3 month trial" started.

However, you are under no obligation to tell your employers early! I would definately wait until 12 weeks. Or you can wait even later. Remember to say you are happy to continue working part time during the pregnancy (assuming you are).

I'm not planning on telling my employer until maybe even 20 weeks after we conceive. (I'm pretty fat so I can hide it well I'm guessing). This is becuase of the end of my contract is coming up and I don't want me pregnancy to be an issue it in not being extended. I'm just going to say that we were waiting for the 20 week scan to check everything is okay (hence alluding to the fact that we might have been concerned for the baby's health and they can't aruge with that!). E

veryone's situation is different though and you have to gauge whether or not your boss would be annoyed or suspicious of you for not telling them earlier....
