I bought abortion pills online

We do not recommend that you take medical abortion pills without being under the supervision of a trained family planning professional.

We would advise you phone Marie Stopes before taking your first set of tablets. If you're from the UK, you can have an abortion under the NHS. If you have taken the pills and are concerned, please call our advice line or see your GP. 

Please read our Medical abortion explained section for in-depth information and advice. 

If you're unsure whether you want an abortion, we can provide abortion counselling
