Last night I noticed I have a sore like buldge on the bottom of my tongue. I wouldn't have noticed it if my significant other and I weren't kissing and noticed the bottom of my tongue hurting. It was hurting because it was scraping on one of my teeth. I am 38 weeks and it is still under my tongue an is sore I was going to wait till Tuesday to talk to my Dr about it but I honestly don't know if it something to be concerned about or not. I tried to look up salt blister but it gives me information about cold sores. Any information would be helpful.
