Yasin was conceived in my second month off the pill but because I was away for a lot of the first month the second month was really the first month of TTC.
After Yasin was born we never used any contraception but nor did we actively TTC until he was about 6 months old. We conceived Imran in our third month of proper TTC.

ETA - I think second babies can sometimes take longer because there aren't so many chances to DTD.
