Trying to get pregnant after DEPO

Brittany
Alright ladies. I need some stories/advice. Maybe just to see if other women are dealing with the same thing. My husband and I have been trying for 11 weeks to get pregnant with no luck. We have sex pretty much every night. I did have a period after stopping depo but haven't had one since. Negative pee tests and negative blood tests. We are so disappointed. I'm wondering maybe it is the stress I am under? I just lost my dad a year ago and my mother just passed away from cancer this October, so I am under a lot of stress. But anyway.. We tried preseed once but I didn't keep up with it so maybe I will continue that every single night again. 
My question is that are there any women out there that have had any luck getting pregnant after stopping depo? I know it can take up to 18 months to get out of your system but just curious since everyone is different. 
Thank you in advance!
