When does spitting stop?!?

Karen • Mommy to David, Robert. Maybe this is a girl ?

I have been spitting since I was around 14 weeks and can't stop. I've basically come to the conclusion that I'll be spitting until I give birth but how soon after giving birth will I have to wait? 

Edit: I understand what I'm spitting out and I'm heading into my 3rd trimester now so this isn't a new thing. I'm trying to see if there is anyone who went through this that can tell me how long after giving birth, they stopped having to spit.
