I took my temperature yesterday (8/29/15) morning before I got out of bed and my temperature was 97.52. Last night round 1030pm, I took an ovulation test and it came out positive. (Pic below)
This morning (8/30/15) my temperature was 96.87. Hmmm how is that? I don't understand it?? All of my app says different fertile windows. So my boyfriend and I just going to BD anyway just in case one of them wrong.
