Pink discharge

I just got off my cycle about a week ago right after if was over I got sick with the flu and I felt a lot of discomfort and cramps it felt like actual period cramps but I wasn’t bleeding. Now three days of this and I’m starting to feel better so I had sex, later that night I go to pee and my discharge which is normally very light or clear is now pink I’m not sure how to feel about it can anyone help?
