Hello my dear,
it sounds to me like early stage and mild changes might actually be two ways of saying the same thing. Mild changes ARE the first signs of cervical disease, and if I have read everything I have googled (!!!) correctly, they changes are almost always brought about by HPV infection, although I am still trying to take that one on board!
i know that personally I think I have ended up with this diagnosis because I have been under significant stress for a number of years, which will have left me vulnerable to the HPV raising it's ugly head. From that perspective, is it possible that your cervical changes and your conception issues are linked through stress? Trying to conceive can be very stressful, as can going for colposcopies etc!
I am struggling to lower my stress levels (wonder why!?) but I am going to keep working on it! Also looking for other ways to boost my immune system. I find that being proactive is in itself a good stress reliever. Sometimes!
best wishes, take good care of yourself and try not to worry about those changes, they are keeping an eye on you And nothing will develop too quickly.
