Stomach pain caused by my cough?

The past couple weeks or so I've had a cold. The nausea went away but the cough is still lingering. When I had the cold, when I would cough my throat would hurt and after awhile I had back pain. Which I assume is normal. But now, whenever I cough, I get an unbearable stomach pain. The pain is in my lower abdomen, right about my pubic area. It's like a sharp stabbing pain that last for only a very seconds. But sometimes it hurts so bad I double over. I'm young, and am very healthy. I rarely get sick. I'm on no medication other than birth control and depression meds. But it only happens when I cough. Tell me, should I get this checked out? Or am I just worrying for nothing?
