I keep having cramps in my stomach not to sharp but very often, does anyone know what they could be?

Okay thank you I've been having them for some time I ask my doctor last visit he said if I was having 10 an hour to come in, I am but they aren't as sharp as they usually are @rylannsmommy2016 I freak out over every little thing

How do you know if you need to go to the doctor or not @rylannsmommy2016
