Hi, I m 30 Weeks Pregnant and everything is going smoothly. 2 Days ago my tongue started to swell up, it has remained swollen, although doesn t really hurt, it s just annoying and a bit uncomfortable. I ve been drinking lots of water to keep my mouth lubricated as it seems to be drying out quicker than normal. I do have a small ulcer on my outer gum, but it s not painful at all. I haven t eaten or drank anything different. Any Ideas??
