Re: review
There's nothing to stop you asking for a salary review at any time. Rather than just going into your manager and blurting out that you want a raise, perhaps you word it as a request for a performance review. If he/she asks why, you could then say that you hadn't had a pay rise in XX months and wanted to know whether this was in any way attributable to your performance.
If there is an issue with your performance, you should at least get some specifics on the aspects of your performance that are being negatively perceived along with constructive advice on how to address the issue. Seek specifics - don't accept the use of phrases such as "I feel..." or "My gut feeling is ....". Problems with your performance should be based on specific examples - otherwise it's useless and condescending.
If there is no problem with your performance, you can reasonable ask for a pay rise on the basis that other people are getting one.
