Douching with water PP?

Does anyone know how long after birth you should wait before douching with warm water? I only use water (no products or anything) while in the shower. I'm 1 month PP today and did a light rinse in the shower and now I'm feeling kinda crampy. Trying to determine if it could be related or not. The doctor's office is closed, otherwise I'd call them and ask.
