If a woman was about to be promoted and found out she was pregnant before she signed a contract and didnt tell her boss, is she committing a crime?

It is not a criminal offense to refuse to disclose private information.  This may or may not be grounds for terminating the contract, but it is not a criminal offense. This is not intended to be legal advice, and is general in its nature. No attorney-client relationship exists or is formed by this information.
