Sharp pain in uterus area


Lately for the past year I've been getting these sharp pains in my uterus area. They don't really have a specific time period. They happen randomly. Sometimes they will happen during my cycle, or sometimes not even close to my cycle. Sometimes after or before it too. The pain is usually a very sharp pain that lasts about 2 seconds but its so bad that it leaves my knees weak. But the funny thing is after the sharp pain ends, it feels like nothing ever happened and im completely fine. Does anyone experience anything like this? Or am I the only one?
