After using emergency contraception (e.g. the morning after pill), the body may temporarily react with various changes in the cycle, including a change in the consistency and color of the mucus. Yellowish mucus, if it is odourless and without other symptoms (e.g. itching, burning, pain), can also result from changes in the vaginal bacterial flora, the presence of blood residues or natural changes in the cycle (mucus may be more yellowish in the luteal phase or after ovulation).

If the mucus is odourless, without lumps, and is not accompanied by itching, burning or pain, then infection is unlikely. Pharmacies also offer tests that allow you to rule out an intimate infection, e.g.:
