Today is cd 10. I got the following opk's (use clear blue advanced): cd7-high, cd8- peak, cd9- peak (used another holder) & today- low. I had very wet, slightly stretchy cm on cd 8. Wet cm yesterday but slightly sticky. Haven't checked today. Temps have not risen yet. However, I just went to the bathroom and noticed some spotting on my underwear (looked brownish but hard to tell since underwear is pink). Has anybody ever had this spotting? What does it mean? I know it's too early to be implantation bleeding. Could it be ovulation spotting?
