Getting pregnant after a multiple pregnancy

Good morning ladies,

I'm new to the forum.
My husband and I have decided to go for a third baby, of course I'm absolutely thrilled!! At the same time, I find it super exciting because our first two kids came at the same time... It's a fraternal twin set, so there's a chance that the third one (if I'm lucky enough to get pregnant again) won't just be a third, but also a fourth!!! Whatever happens, happens, that's how it is, but that of course has quite a few consequences (just think about the childcare costs doubling)... Are there any moms here who got pregnant after a multiple pregnancy?
