Okay so I was on the depo for two years after I had my daughter. I have been off the depo since April. I haven't really had a period since I got pregnant in 2015. Last month I had a good heavy period for the first time in three years that lasted for 5 days. According to glow I am suppose to start my period again today well I didn't so I took pregnancy test negative of course. Me and my boyfriend have been trying to have another baby since April when I got off the depo. No hope. Does anyone have any tips on how I can get pregnant? Or how long did it take you to get pregnant again after being on the depo?
