This might be something and nothing but I just went to the loo and wiped and got pale pink CM, slightly darker than flesh colour I guess, only on the loo roll. I thought maybe it looks pinky but is actually due to strong urine but looked in loo and urine was very weak. Did internal CM check and no sign of pale pink CM - just clumpy white CM with a tiny tiny bit of stretch.
​I haven't really been having any noticeable cramps, few twinges here and there..
​Am I just imagining tan CM and if not, what might it mean?
