It could be just a blocked duct but I saw yes get it checked. Our lil ones are stronger than we think, especially the farther along you get. I was worried because I lost my gradmother this summer and was only 10 weeks. I will be 21 weeks tomorrow :O) good luck
Call your doctor and have that checked out. Could just be a swollen gland but better to be safe than sorry!! Good Luck!!!
I think you should call your dr.. I'm sorry you are dealing with such stress..
take care
