Excessive saliva ?

Jovian • Age 26
So I'm currently 12 weeks pregnant with my first bundle of joy ? . One thing I have to say that I can't stand is this excessive saliva I've had since I was about 7 weeks pregnant. I constantly have to spit because I don't find the taste of my saliva ( weird I know lol ) Has anyone else experienced this ? How did you deal with it ? It's driving me crazy !!
