fertility issues?!?

Gabriela • First time mom. 23. Due 06.26.17
My bf and I are really trying for a kid.ovulation test and preseed and we are currently doing it on my fertile week. I am just a bit worried, bec although i'm 23 i have had problems getting pregnant in the past. I have been on the shot, birth control and iud about 4 years ago.  And I'm worried that it could have cause me permanent difficulty in having a baby. I'm trying not to stress or worry but I really hope I'm pregnant on this cycle. 
Thanks
