Return to ovulation and fertility is likely to be delayed after stopping Depo-Provera. It is expected that 68% of women who do become pregnant may conceive within 12 months, 83% may conceive within 15 months, and 93% may conceive within 18 months from the last injection. The median time to conception for those who do conceive is 10 months following the last injection with a range of 4 to 31 months, and is unrelated to the duration of use. Amenorrhea and reduced menstrual bleeding generally normalizes maximum within 5 - 6 months. You should consult an Infertility Specialist, and have a thorough check-up, hormonal tests, semen analysis of partner, ovulation studies and fallopian tube testing. Take care. </s>
