Super weird discharge after masturbation

Last night and tonight I’ve experienced something super weird with my discharge after masturbating. Everything was fine, I finished and then I got extremely watery discharge and it just wouldn’t stop coming out to the point where I thought it was pee, but it was coming out of my vagina and not my urethra, and it doesn’t smell like anything. And tonight I experienced cramping afterwards. Does anyone know what’s happening??? I’m more than a little freaked out.
