ttc after miscarriage

I was on the implanon for 3 years, the Nexplanon for 2 1/2 when I decided to ttc. I got it removed on July 9, had a scheduled normal period on July 11 (obviously still a BC period) on August 5 I started a new cycle and could tell that the BC was out of my system because I had bad cramps and it was heavier. well on August 31 I found out I was pregnant I was 3w4d when I found out. on September 9 I was 5 weeks exactly and I miscarried. the dr said I was good to try whenever I felt the time was right. I was just wondering what yalls experience was. *I got pregnant at 17 and he was perfectly healthy and had a healthy pregnancy. this was only my 2nd pregnancy so I'm scared to try again and have it happen again.im not sure if it was because of the Birth control or what. any advice is appreciated. TIA
