depo provera

chloe
ok so, i've only been on the shot since june 27th, i got it in the middle of my period and i haven't had a period since then lol. but anyway so me and my boyfriend have had unprotected sex multiple times. now i'm having light brown discharge every so often and some cramping and white like mucusy discharge too. 
i'm a little scared bc i've had a lot of pregnancy symptoms, but all of the symptoms are also the depo symptoms. 
i just wanted other people to share their times on depo bc i'm a little terrified that i'm pregnant.
