Symptoms before your missed period

For all you lucky ladies who have already conceived.... Did u have any symptoms before your missed period? I have been so tired, nauseous, no longer interested in drinking coffee (which I love) and had some spotting earlier in the week. I tested negative but it's too early AF is expected in 7 days...... I'm wondering if it could be the real deal or is my mind playing tricks on me! I'm so impatient!!!!!!
