I am new to all this as well. I dont use ovulation predictor kits because I have irregular cycles, but from what I have learnt, they tell you when your body is preparing to ovulate. You may have the surges in lutenising hormone that indicate ovulation, and get a positive test, but you might not actually ovulate at that time. Are you charting your bbt? If not, I would recommend buying a fertility thermometer-$20 at chemist, and chart your early morning temps (also known as basal body temperature) in combination of OPK's. If you get a positive reading with opk, and after a day or two your temps go up around half a degree or so, then ovulation has occured. I am not sure how to upload your chart though. I use a samsung galaxy tablet for this cause hubby is a gamer and computer hog, I took a screen shot of my chart and added it as an attachment to my post. I used fertility friend till I had to pay money for it, then switched to Ovuview. Although I did really like FF, and would have paid if hubby didnt say its a waste of money. Did FF interpret your chart with the OPK's? That is I feature I really miss, saves all the guesswork. Kay, enough with my blather, hope I helped in some way, and just remember, as long as you are getting positives with OPK's, just keep trying!
