i want to get the pill
I guess the first decision that you will need to make is whether you prefer the combined pill (with two hormones oestrogen and progestagen). You can see more information about them here:
You need a prescription to get the pill - so you can get it from your GP, or sexual health centre. If you live in the London Boroughs of Lambeth or Southwark then you can order it free online.
If you have any questions about the pros and cons of the different methods then do let me know.
