ovulation woes

Leighanne
I am cd 13 and tested positive this morning (Wednesday) for peak fertility/ovulation (non flashing smiley face) on a clearblue opk. I didn't think I was supposed to O until Friday (cd 15 my usual O day) and my SO is out of town and can't get home until tomorrow night. . .Do you think I still have a chance??? I'm recording my bbt and no temp rise yet. I was thinking maybe I have a chance since the test stays positive for 2 days it predicts O occurring within 12-36 hours. I will accept and appreciate any and ALL advice!!
