Are there any side effects ?
Many women take emergency contraception and have no problems with it, but as with all medicines, it doesn’t suit everyone and there can be side effects,
The most common side effects from Plan B One Step include:
- feeling sick
- abdominal pain
- menstrual changes
- breast tenderness
- vomiting and diarrhoea
After you’ve taken Plan B One-Step, you may also have some unexpected bleeding. This should go away by the time of your next period. Sometimes Plan B One-Step can affect your next period, making it heavier or lighter than usual.
Your period may also come later – or earlier – than expected. If you haven’t had a period after three weeks, take a pregnancy test just to make sure that you’re not pregnant.
