Depo shot

Sarah • My husband and I have been together for almost 7 years. Married 08/09/2014 💑 M/C on 03/05/2016 💐 We are ttc for our little rainbow ❤💙💚💛💜💕
Has anyone ever had a hard time ttc with the depo shot? I only had 1 shot, but my period still hasn't started after a month. My gynecologist told me that even with just one shot, it can take up to 18 months to get pregnant and said a lot of women have a hard time ttc after getting off of it.
