Did excessive saliva last the entire pregnancy for you ?

I been having to walk around with a spit cup since week 7. I’m 19 weeks currently with babygirl. I’m TIRED. This spit is getting out of control to the point the whole cup is filled after only an hour🤦🏽‍♀️ I even woke up 2 nights choking on my own spit. my boyfriend is so mad
