Pain in my tummy

I have this pain in the right side of my tummy which feels like it is going to rip open. It also feels like something is slowly slicing my side. I guess this is just a normal feeling specially for a growing tummy since I am at my 28 weeks of pregnancy. I searched online for a similar question asked by other pregnant women and most of them say that it's just a normal feeling and it is due to the stretching of the uterus to give more space for the growing baby inside the tummy.
