I am 7 weeks pregnant and i constantly have this sweet taste in my mouth and i nolonger eat sweet thing , but the taste is always there how can i trea?

Taste & smell...: ...sensitivity & other changes are VERY common early in pregnancy but usually get better by the 2nd trimester. You might also have reflux, another common pregnancy problem. OTC antacids like Tums (calcium carbonate) & Rolaids are safe during pregnancy. Pay special attention to your oral health, take your prenatal vitamins and stick to mild, easily digested food for now. Best wishes for a healthy baby!
