Contraception

I'm worrying that after being on my pill constantly for 13 years is going to affect my chances of becoming pregnant. We have been trying for 6months almost and suffer from anxiety and I am prone to thinking into things too much. I am 27 years old, fit(ish) and healthy. Will the constant use off the pill since I was 14 affect me (I was put on the pill due to my period pains and the doctors never changed my suggested contraception)
