we have just started trying for no 2. it took us 14 months to concieve Archie, we got positive test 2 weeks before our fertility tests so we we don't know if we do have a fertility problem or not. We would have stared trying at 5 months, cause we really wanted them close in age and were worried about how long it would take, but due to DS having servere reflux we decided to wait til that settled down a bit first.

You will 'just know' when you are both ready to try again, goodluck with everything!
