When your consultation was confirmed, you would have been sent an email with a link and information regarding logging into the Fertility Consent system. You need to follow the appropriate clinic link and enter your medical ID (this is your Bourn Hall medical number and not your NHS number) and your password.
Cambridge – http://bhc-cambridge.fertilityconsent.com/
Norwich – http://bhc-norwich.fertilityconsent.com/
NB: Unsure which link to use? The safest rule is to go by your case number – if your number starts BN, you are Norwich; BW – Wickford; and no prefix, so just a number, then Cambridge.
