Hello I am currently having a sharp pain

Patient: Hello I am currently having a sharp pain that starts from behind my belly button and it connects like a string all the way down to my vagina. It hurts so bad that I cannot stand up straight. I have always had this pain since I was 12 years old, it comes and goes at a random. I was wanting to know if anyone can give me an idea as to what this pain is or if it’s even normal to have?Also: I am not pregnant, and have never been pregnant. And I DO NOt use any forms of birth control.Thanks hope someone can help soon……. 🙂
