Little advice please?

So I was on nexplanon for 3 years, had no periods the whole time I was on it and I got it taken out in April of 2017. My bf and I have been TTC since January with no luck. I have very regular periods and I ovulate. I even use OPKs. Both of us are healthy and capable of having children but it just hasn’t happened yet and it makes me really paranoid like what if I never can get pregnant? My sister told me that it’s the birth control i was on that messed w my body and fertility and that it takes like a year to get 100% back to normal and not to worry about it too much. Thoughts? 🤗
