I have had my first dose of herceptin and had a period afterwards which lasted my normal 3-4 days. Whenever I do anything strenuous I start bleeding again? Its has happened twice now over the past week.
Irregular menstrual bleeding is not a known side effect of Herceptin, however it may be causing it. Please discuss it with your specialist ... they may have seen this sort of side effect in other patients.
