We got off birth control when I was 27 or 28 and didn't conceive until 31.
But our fertility issues were male-related, which we knew due to testing.
Getting pregnant at 33 happened much more easily. Could be because things changed with him, could be because once you've been pregnant once, it's supposedly easier to get pregnant again, could have been a simple matter of timing.
