everyone speaks of a metal taste as a symptom of pregnancy. Has anyone ever had a sweet taste, that doesnt seem to go away? Im not eating loads of sweet things although over christmas I have indulged a little. Now 22 wks and due for glucose tolerance test at 28 weeks. Have had this sweet taste for probably last month. Worried that it might be a symptom of Gestational diabetes or something. Im pregnant with my third, worried as my second was 10lb 14oz!
