I was convinced i wasnt going to ovulate this month, usually I ovulate day 12-14. I use a clearblue fertility monitor. Been getting HIGH readings since day 9. Day18 yesterday and i got an almost positive (ie faint) opk.. So I expected a PEAK reading on my clearblue fertility monitor this morning (day19) which i did. But... Usually I would then get a positive opk today to back up the peak reading (and pin down a more exact ovulation time) but... Today i didnt get that confirmation. I did 3 opk tests (cheap internet ones that usually work just fine) throughout the day but I got 2 faint tests and tonight completely blank! So... Do u think I ovulated last night since my "almost positive opk" noon yesterday? The negative opks today mean ??? Thoughts please ??
