Whenever I try to run my side hurts

Hello, so recently I’ve been trying to start running and jogging for fun and get into it but whenever I start after a minute or so my side starts to hurt ( like on my right side just around the more lower part of the rib cage) and I stop. This always limits my runs to about 1:30 or 2:00. I’ve tried to control my breath and it helps for about 20 seconds and then it starts hurting again. Do I simply just need to exercise or stretch before hand or what should I do? Thanks!
