樓主, how old are you? if you are over 30, please don't hesitate any more. give birth right now!!
i had my first at 36, and regret to not giving birth earlier. (but when i was young, everyone around said 有仔趁lun生, 我當耳邊風)
don't give up the dream of having kids just because your husband doesn't like kids. they still can change their minds at 40 or 50, but you can't. if you really like kids, do it.
P.S. there is no one perfect timing to giving birth. life is full of compromises. you and your husband must make adjustments to your life and give up something, may it be time, money, job, freedom. but i can assure you it's all worth it.
