Pink discharge

Latasha

Last had sex a week before my period. Period came and went as normal. Two weeks later pink discharge for a couple days. Went away and now returned. Now I get crampy about two weeks before next period but I cant tell if the discharge smells bad to me bc its mixed with urine or if I have possibly an infection. I hate going to dr for lady bit problems but I guess I will have to go. Guess I’m just spotting? I take birth control everyday on the dot btw
