Planning but unsure

I am planning on wanting another child. I have a almost 3mo in the house, but I don't want kids close in age, but I miss the feeling of being pregnant, I loved the feeling of being pregnant, choosing out names, finding out that age old question "is it a boy or a girl?", etc. My boyfriend has talked to me about kids, and I have too. But I keep pushing it when ever he tries, I'm scared I might push him away for good, what can I do? Please help me, I am in need of help for this.
