Leep procedure questions... I'm scared.

so yesterday I had my 2nd colcoscopy. according to the doctor I may need a loop electrosurgical excision procedure aka LEEP done. I am scared. I'm 24 & I have no kids yet. I'm scared of how or if this could effect my chances of having kids or just complicate things down the road. does this procedure hurt more than a colcoscopy? I just want to know has anyone had one of these done? If so did it complicate anything for you?
