Thanks Elspeth, glad I asked though now feel slightly stupid. The first noticeable colour (dark brown) I think was about Monday -1st sept (had not been dabbing every day so could have been a day before, partly why I feel stupid though pretty sure was Monday that colour started) so a week ago and getting a little redder and less brown as the week went on and the brighter red started yesterday 7th sept. Any way she's not yet trying to get out ect.
Edited to add: Thinking about it I am sure she started Monday remember dabbing on Sunday, and it is now getting a bit heavier.
