Hi, I had my baby 8 weeks ago by C section. For the past three days I've noticed a blue/green stain in my knickers. I've never seen anything like it before. I went to the out of hours GP yesterday and he tested my urine, which showed no signs of infection. I've googled it and only found one other person who have had this which she reckons was down to a change in hormones after childbirth. I just wondered, has anyone else had this happen to them? Thanks, Sarah
