I think it depends on the woman, I felt my cervical position the morning of the day I did my test and it felt quite high but also a little harder. So I thought "AF is on the way" but then my tests turned up (bought them off amazon). I almost nearly didn't bother doing one because I had a little brown cm and the harder feeling cervix but I got a BFP. My point is I think it's different, text books would say it's soft and high, but that isn't always the case. Mine is now high and soft but I'm not sure when that happened xxx
