Does anyone feel pain right under their breast?

It feels like rip pain. I feel it only on the left side. Sometimes it only hurts a little, sometimes a lot (esp after I eat a heavy meal). 
I'm only in the fourth month of pregnancy. In fact, I've been feeling hurt there since I was at the beginning of the third month. I heard that it's common during the third trimester. 
It doesn't feel hurt all the time though. It comes and goes... I don't mind the pain as long as it's not a sign of a serious health issue or poses harm to my baby. Does anyone have the same symptom? Is it something normal or should I be concerned?
