Ttc number 2

My so told me the other day that he wants to try for our second child. I wish he told me this before i had the shot Aug 19th this year. I am getting nervous seeing how much trouble people are having ttc after depo. Ive had 2 miscarriages in the past year and have a history of ovarian cysts and uterine polyps. I hope that doesn't hinder us any more than this depo. How long does it take for the depo to wear off and for my body to be get ready for baby number 2? Any suggestions will help. TYIA!
