Depo provera

For those of you TTC or have conceived after depo:

How long did it take you? My last injection was 18 months ago, I have regular periods and ovulate monthly (for the last 5 months in a row) I don’t know why I can’t get pregnant. I do have low progesterone, but I’ve been treating it. My luteal phase is 14 days and I never have spotting.

Was there anything you did that helped you conceive?
