I got mine through the hospital team at one of my scan appointments - is pop in and ask them if you are struggling Xxx
I just went to the pre-natal department and asked the receptionist because no one was answering the phone and told her it’s urgent need it for work and they got a midwife to sign it for me that was at Tameside
