I've had so far 5 +opk (darker than control line). I had a small temp rise on cd13 and a more significant temp rise on cd15. Problem is I haven't been sleeping well, so I really can't trust that my temps are correct and I wanted to know if I had on the right days. This month I tried a ferning microscope and I had entered some observations on FF. However, I never figured out the ferning thing so I stopped testing. Today FF gave me dotted lines because it said microscope did not correlate with opk, so I took out the data I had entered about ferning and FF then gave me the crosshairs without the dotted lines. (BabyMed gave me crosshairs for the same days.) However, I am still wondering, because the first temp rise was so subtle (only 0.2 degrees) and I'm still getting +opk's. Could you girls look at my chart and tell me what you think? I would greatly appreciate it. Thanks.
