The short explanation
Nausea, breast tenderness and light spotting are among the most common side effects in the first few months of the combined pill. For many women, these settle within about three months as the body adjusts. Taking the pill with food or at bedtime may help nausea. If side effects are troublesome or continue beyond three months, talk to your doctor. There are many types of pill with different hormone combinations and strengths, and switching can help. It is important not to stop suddenly without another method, because you could become pregnant.
What depends on your situation
The parts of this that change from woman to woman. Uncertainty is stated, not hidden.
- Spotting is more likely if pills are missed or taken at very different times, or with vomiting or diarrhoea.
- If spotting starts after months of normal bleeding, or happens after sex, it should be checked for other causes.
- Some side effects need urgent attention, such as leg pain and swelling, chest pain, breathlessness, or a sudden severe headache.
What this answer cannot determine
The boundary of online education. These need a clinician who can see you.
- This answer cannot tell whether your pill is right for you. Your doctor can review side effects and options.
Questions for your clinician
Take these with you. You can add any of them to an appointment card.
- Are my side effects likely to settle?
