When you say cycling, do you mean just running the filter with water, or have you been adding ammonia? If you haven't been adding a source of ammonia, your tank isn't cycled. Also, slightly pink doesn't mean anything without knowing what kind of test you're using and what you're testing for. Read up in MissFishy's link about cycling, and when you're ready to post test results, please post numbers for ammonia, nitrite and nitrate. So, the short answer is, no, you shouldn't add fish yet unless you want to do a fish in cycle.
