I'm having a similar issue with brown mucus. It's my first cycle off the Pill and there's been a pinkish-brownish tinge to my CM for the past few days (CD 10-13). Just now I had what I would think is EWCM but it was mostly BROWN! I had a strong cramp yesterday which I assumed was ovulation. I'm worried that the persistent pink/brown means I'm not going to have a good enough lining this cycle, even if we did manage to fertilise my little egg.

I haven't been temping, only doing CM Obs, so even if I started temping now I possibly wouldn't detect a rise (it may have already happened). Maybe I'll go buy a thermometer now anyway.

It's going to be a confusing TWW...
