I know there is a opk forum too, but this place feels more like home to me so I hope you all dont mind me asking this here.. I got Wondfo OPK this cycle, and I have never used them before- I always have used the ones from early-pregnancy-test.com and with those it was pretty easy to see my surge... I am CD10 today- Got the Wondfos delivered on Sat, so started testing to get an idea of how they work, how faint ect.. Well this morning, I had one that looked pretty dang close to positive to me- then this evening I asked hubs and he was like.. oh thats positive for sure- which i tend to agree with! I most generally ovulate on CD13 or 14, so this seems early for me... but I guess totally possible. So for those that have used these.. are they ultra sensitive? do they get MORE positive than this? would you consider this for sure a positive or just pretty close? The picture is the four tests lined up- Top is from Sat afternoon, then sunday late morning- Then third is this mornings, and last one is from tonight. Thank you ladies- it helps so much to have people to take this journey with!
