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.
