- Breast tenderness
- Irregular menstrual bleeding may occur for a few people. This means that the pill can sometimes cause changes in your menstrual cycle. Your period may come earlier or later than usual, and the flow might be different (heavier or lighter) than normal.
Very rare side effects, which might affect up to 1 in 10000 people, are rashes, itchiness, swelling of the face, abdominal pain, and a painful period.
Inform your doctor if you are experiencing any of these symptoms or feel like your body is not reacting normally to the pill.
