Quick answer

Side leaks usually mean the pad is too narrow or not positioned correctly. Check your wing placement and pad width first, then consider a thicker pad for heavier days.

Wing placement is the first thing to check

If your pad shifts or the wings are not snug, gaps form at the sides. Make sure the wings wrap fully under your underwear and the pad sits centered over your gusset. A quick adjustment often stops the leak without changing pads.

Pad width and absorbency trade-offs

A regular pad is ideal for average flow days, but if you have a heavier flow or a wider gusset, you may need a wider or thicker pad. Wider pads offer more coverage but can feel bulkier. Thicker pads hold more but may be less discreet. Choose based on your flow and comfort.

Diagnose and fix side leaks

  • Symptom: Leak appears only on the sides, not at the front or back. This usually points to a fit issue, not a pad failure.
  • Likely cause: The pad is too narrow for your gusset, or the wings are not fastened securely. Check if the pad covers the full width of your underwear gusset.
  • Corrective action: Adjust wing placement so the pad sits flat and snug. If leaks persist, switch to a wider or thicker pad for heavier days. If the pad still leaks after adjustment, try a different size or absorbency.
  • When to stop or choose another option: If you have tried a wider pad and it still leaks, consider a different pad shape or a menstrual cup for additional protection.
