How soon is too soon

Kai
So i just met this guy and we're on the same page with everything. I told him i want kids and asked him if he was ready to have another baby or two so soon again (he already got two kids of his own) And he says yes. I haven't had sex wit him yet but i wanna just jump right in and do it. We won't have no issues taking care of the kids, he's a provider and of course imma still have my own coin lol. But I'm mentally stalling because what imma say to my family if i did get pregnant soon after meeting him? Kinda still have a child factor in me even though I'm grown, 24 and responsible for my own decisions. They've always told me you better not get pregnant. And maybe that's why i never conceived . im getting older and don't wanna waste any more time. This is what i want .
