It can easily take an orchid a year and a half or two years until it blooms again. Just make sure it's getting plenty of light, and only enough water to keep the soil slightly damp. There are orchid fertilizers at plant stores, and it's a good idea to use one, because orchids don't like to be repotted; they like their roots to be crowded. Feeding your orchid will keep the soil from becoming depleted of nutrients over time. Follow the directions on the jar. Above all, be patient. As long as you're seeing new growth, either leaves or root shoots, your orchid is alive, and eventually it will bloom again.
It may be because the weather outside is not right for the flower to bloom yet. Usually, flowers have certain seasons at which they blossom. Don't worry though - the three new leaves shows that your orchid is alive. Just be patient. :) Hope this helps!
