Hi. I've never noticed before but today, CD 10 I had a little very light brown discharge in my panties, kinda mixed in with regular creamy CM. Wondering what this means. GLOW has my most fertile day on Sunday, today is Wed. My Love us out of town till Friday. Am I missing my window or could this be something else? I've started several new vitamins, including a prenatal, magnesium, wild yam, cranberry, and fibre pill in case they might be the culprit. TIA
