I am 15 weeks pregnant with my fourth child and once again I've had a big problem with toothpaste and morning sickness. It was the worst with the first pregnancy, basically, I would feel a bit queasy before brushing and as soon as I cleaned my teeth I would throw up. As in the other pregnancies I've also gone off a lot of my favourite high salicylate foods and am completely unable to handle caffeine and chocolate (makes me very anxious and heart palpitations). – Julia
