Something wrong?

I having extreme stomach pain. Every morning i get it. Its like these really intense cramps. This has been happening for years. I dont know why this is happening. This scares me because i dont know if ill be able to carry kids if i want to because the cramps ate that intense. Has anyone dealt or is dealing with this right now? It only lasts for about 3 minutes or so. This happens every single day i cant eat breakfast because my body wont allow it. Is there something wrong with me. Im 16 btw
