Pregnancy and birth control

Sarah • 27. Married. My son was born 2/22/16 and his little sister 7/5/17
I have never been on any form of birth control IUD or pill, or shot- we simply have only used the pull out method- so when we started ttc I thought it would be fairly easy for us considering I never did anything to alter my hormones- but now, I'm wondering if people who were on a form of birth control and then stopped taking it to ttc have it easier because my train of thought is that maybe the sudden shock of discontinuing the pill puts your body in a better fertile state. What are your thoughts ?
