Trying to get pregnant after years of BC

Erica
I've taken birth control pills faithfully for 9 years. I am now 30 years old and I am off the pill. My husband and I are officially trying! 
Has anyone else been in a similar situation? Just wondering how long it'll take to get pregnant. I have a feeling because I was on birth control for so long that it will be at least 6 months - 1 year. Thoughts?
