Clare - Sorry, but i can't help you with the back pain, but the EWCM is the best sign for predicing ovulation. Could it be that maybe you just pulled a muscle or something. Good luck and i hope you catch that eggie.....

PS. I love your DD's name. I've always wanted to call my daughter Shelby after seeing Steel Magnolias, but when i mentioned it to DH, he didn't like it. Oh well, i'm still waiting to get a baby and by that time maybe i can change his mind. Love it...great choice...
