I'm 22 weeks and a few weeks ago I found a softball sized ball in the lower left side of my abdomen that comes and goes. Went to the dr this weekend and she said its probably a hernia. Being it comes and goes and isn't painful, it shouldn't be a problem. If I still have it before I deliver, I will have to see a surgeon before and they will take care of it with mesh during my c-section (this will be my 3rd c). Just curious if anyone else has had this during their pregnancy.
