Wow that is a bit rough Gemma! Your the one who has to carry the baby not him!! What if you don't cycle next month? What if you don't cycle for a few months!?
I have to admeit I wanted Emily and Violet to be closer in age, but that didn't pan out, I didn't start cycling until Emily was about 6mo, and even then my cycles were really long.
Also I have read that studies into pregnacies really close together (b4 the baby is 6mo) there can be a risk of premature birth, miscarrage and I think maybe birth defects (not sure, maybe do a search)... so if you don't want to be pg again so soon... use these findings to your advantage
