I just got off implanon and got pregnant 2 months later. Will this effect my baby?

Has anyone been on implanon and got pregnant so soon? I am very concerned about it. Also, does being on a birth control like this effect your cycles? I only had 2 periods before I got pregnant so I have no idea what my cycles are like. It is hard to pinpoint when I conceived. I am very worried I got off this birth control and got pregnant so soon!
