If IVF worked once, will it work again?

Hi all,
In Feb last year I did ivf icsi and was lucky to conceive on our first attempt. The ivf process was fine for me and everything went well. Unfortunately half way through our pregnancy a scan revealed problems and our wee girl was born in October but passed away a few weeks after birth. We are so heartbroken and miss her everyday but we are determined to not give up on a family.
We have been fortunate enough to be granted another funded cycle which starts in March. Part of me is excited, then another part is petrified that it wont work.
I know should feel positive as the first go worked and I carried our baby till term.
Has anyone got any success stories of conceiving twice, three times etc via ivf icsi, or is it really just a gamble?
Thanks in advance.

Hi farfella,
tha k u so much for your message. That gives me so much hope just reading that! I have days when im really positive then days when im not. I think the closer it's getting the more nervous I am. But I am hopeful too, and yeah my body had no problems with ivf or carrying a baby to term so I guess that's in my favor. Thank u so much
