thanks! I actually just compared this test to the ones from last cycle which i saved on a piece of paper and labeled by cycle day..my cd16 test looks identical. And that ended up NOT being a positive, but it appears my body gears up to o on cd16 and then doesnt, and then I o 5 days later. I am going to bd just in case though! cant miss that egg! last cycle i had a huge temp dip the day of my positive opk, and then it went up again the next day and continued rising. i am having some temping issues this cycle bc its summer and my bedroom gets super hot and i wake up overheated every morning---not sure how to account for the weirdness
