I'm 24 weeks pregnant and feel.a bit out of sorts tonight. I had a glass of sainsburys cheap blackcurrant squash that I drunk earlier today and it is tasting g really bitter as if it's had chemicals or something poison put in it! My mouth was tasted horrible after and I had to use mouthwash. Does anyone know what it could have been? No one would have put anything in it and my glasses are rinsed of all washing up water after use
