Hey all 
​My AF is due to come tommorrow how ever I have noticed only today that when I wipe I have clear stringy CM with a tinge of red, just wondering if any one has experienced this, I only ask as I there have been none of my normal signs that AF is comming we are also TTC 
​I normally get bad breakouts and lots of cramping but nothing 
​Any help or advice appreciated  
​Much love x
