Need words of wisdom

Diana • Wife since 5/25/13 first time mom to the beautiful Olivia Rho
Been trying to get pregnant for year half now, first time ever that I have missed a period. Calendar said I was to start on the 3rd and here we are on the 10th and no period. No symptoms of period like usual besides small cramps that come and go. Took a test on the 7th & 10th both showed negative... What should I do now? Help!
