Hello, thanks for using health care magic Yellow pinkish discharges between periods are not a normal symptom together with bleeding after sex. Both symptoms are highly suggestive of a genital tract infection which is most probably chronic. In addition to a possible infection, the symptoms could be indicative of more severe conditions such as cancer. It will be imperative to visit a doctor for detail examination, speculum exam and for tests such as vaginal smear for gram staining, ultrasound to rule out chronic pelvic inflammatory disease, Chlamydia serology etc. You will be put on antibiotics depending on the germ(s) that will be incriminated and the antibiotic should be cyclical for up to three cycles ( i.e. you shall be on antibiotics after each menses for the next two menses that will follow your present treatment) so as to effective erradicate the germ which could use menstrual blood as a good culture medium. Hope this helps you, Best regards Dr Achuo
