Conceiving after being on birth control for 7 years

So my husband and I are preventing pregnancy, I was off for awhile so I used the app to help track my fertility. Now I'm back on nexaplon (which I love) but of course I have baby fever. We are newly weds and I've been on birth control since I became sexually active. I've never been pregnant and a friend who was on birth control got pregnant and it just makes me scared like once we decide to get pregnant will I have a hard time? Does anyone else feel that way? We want children and can't wait to bring them into this world but know we are not ready and just enjoying eachother.
