I think this is something all of us have had to go through at some stage and it really does make you want to just bury your head in the sand!

Try having a sister-in-law who is not a nice person and has caused issues in your family and put your brother in an awful position who trying to bet you to being pregnant and you know she will more than likely win this supposed competition.

And the only reason why she even knows about your situation is by default because your brother should be able to innocently talk to his wife with her using it as ammuntion against your sister! Cause if it was up to me - she wouldn't even be in the loop!

I am preparing myself for the annoucement and her to turn and look at me with that "Up yours, smug, smirmy" look on her face.........................

You have to develop a standard line that you use to anyone saying those kind of things that you can use....It really is the only protection sometimes.
