Depo shot ruined me

Raven
I'm starting to feel like the depo shot ruin my ability to get pregnant or have another successful pregnancy . I never used the depo before my first and my first child is 4 years old now and since after birth , my husband and I use condoms till mid year of 2013 I used the depo . We planned for our second pregnancy after the depo wore off . I found out I was pregnant in March and then I miscarried in May ... No detection of heartbeat and my hcg levels continued to declined ... And I noticed my pregnancy symptoms went away . Ok my husband and I are trying again and no scared ... No morning sickness , just feeling yucky and tired all the time , my breast tenderness is fading away and I don't see my doctor till tomorrow .... I'm anxious ! And worried ! I'm praying that this 3rd pregnancy is successful I'm 6 weeks and 4 days ! I have been reading into some women having issues with producing the pregnancy hormones and having to take pills ... I feel like the depo has ruined me ! :( never again !
