Excess saliva

Since about 6 weeks (now 14) I’ve had so much excess saliva that I spend my life spitting it out; it’s disgusting and puts me off leaving the house. I am able to work from home, but tomorrow I have a meeting in the office which I have to attend in person and I’m panicking about how I’ll cope! I’ve been constantly nauseous and occasionally sick (ordinarily when I haven’t been able to spit the saliva out in time) and wondered if anyone is experiencing this symptom and has any tips with how to deal with it? I’ve tried mints/sweets but they now instantly make me feel sick. With my first I don’t recall spitting constantly, but I did have a horrible taste in mouth for the entire pregnancy. Thanks
