loop excision and a baby

Steph
Hi all, I'm new to this as we're trying to get pregnant and having little luck. My cycles are like clock work and always have been. I already have an 8 year old and now we feel time for another one but we are struggling to conceive. It's playing on my mind to the point we're im thinking literally anything I've been through in the past is causing us to fail. I had a loop excision done just over a year ago (minor operation to remove cancer cells from the cervix) and I can't help but think that is the culprit as to why we are failing. Has anyone been through something similar and still conceived? Or any advice would be greatly appreciated :) thank you xx
