Pregnancy after pregnancy?

What's the soonest YOU'VE been pregnant after pregnancy. I'm three weeks PP and at week 2 I stopped all PP bleeding and we started having sex again 🤤🤤🤤 but not cumming in me. But y'all....for real...I'm having symptoms that I Can. Not. Believe.

Like this shouldn't even be possible...can it? Testing next week because we're four kids deep and I KNOW when my body starts the pregnancy train again 🚂

Btw: we totally wouldn't be all panicked if I was pregnant as we want a LARGE family, but this seems a bit soon, even for us !
