Do you think he wants to get me pregnant again?

So my bf and I have 1 child, she's my world and I'd love to have another. Earlier this Month I told him when I was fertile (cause we were texting talking about having sex) (horny and hadn't seen each other.) *we don't live together.

Then a couple weeks later he plans a vacation for next month for the same day/week that I told him I was fertile. The same time he started planning the vacation he said something about "when we have our next kid" when we were riding in the car one day. He told me the other day how lucky he was that I was the mother of his child. I just thought about this today.
