Hi, Don t get worried reading unfounded stories. Depo shot does not damage your fertility. Although the Depo shot needs to be repeated 12-16 weeks, when it is stopped usually it does not lose its effect in that time period. The effect can last longer because the microcrystals of depot injection sometimes dissolve very slowly. Therefore there is some delay in ovulation and conception. Although pregnancy can occur as early as three and half months after the last shot, the average time for ovulation to start is about five and half months. But the time for becoming pregnant takes a little longer, the average being about 10 months from the last shot. For some women it may take up to 18 months. I hope I have answered your concerns.
