I have had both. When I have used the digital opk's I only get one day of positive. But when I have used the Answer (I think) 20 pack, they look like ph strips, I have had multiple positives. Although I really think that I just read those wrong.
Long story short, no it is not unusual to get only one positive opk. Get to BD'ing though because you should O within 24-48 hours! Good luck!!
