Having trouble getting pregnant & I don't know why

Hi everyone.

When I was 14 I got the birth control in my arm & had it for about 2 years. It started to make me very sick, it made my mood swings UNBEARABLE.. to the point where I didn't even want to be around myself. I got it removed when I was about 15-16 yrs old. I am now 19, about to be 20. My boyfriend & I have been together for almost 2 years and we have been trying to conceive for basically he whole time we've been together. We have unprotected sex about every day if not, every other day & still no baby. I'm a little bit concerned because I know this age is the time when woman are most likely to get pregnant. My periods are pretty regular.. I just dont know if the birth control can still effect me 6 years later.. Anyways, the point in this post is if anybody has any tips on how I can boost my fertility or increase my chances PLEASE please let me know. All I've ever wanted in life was to be a mother.. Thank you
