Thank you so to Mumsie13, Maria, Jane, Annie at Ovacome Support, Tillymint, Sheila and Sara for your very useful and considerate replies and I now understand a lot more about the trial. Your comments have made me think about about the practicalities of being on the trial in a way that had not occurred to me - for instance the amount of hospital appointments, especially with the COVID situation and if control group treatments are available for me on nhs. All things considered I will most probably go ahead with the trial taking a chance feels like the right thing to do. I will keep you posted ladies. I hope you are all ok.
Best wishes Duskygem
