Question Dear Doctor, I am currently more than 3 months pregnant, but due to some circumstances, I have not been able to have an ultrasound yet. For about 2 weeks now, I've noticed a hard lump in my lower abdomen. I can feel it more when I lie down, and it becomes more prominent when I use the restroom. I would like to ask, what could this hard lump in a pregnant woman's lower abdomen indicate, and is it something to be concerned about?
