Why do I have so many positives/ almost positives? I thought it was getting lighter, but it never went back down to what it was when it was clearly double lined negative, and the most recent one this morning almost looks darker than last night's... None of these are looking even close to what my negatives looked like... 4 days?! Pretty sure I had my bbt spike yesterday/today. Went from 2 days ago 97.48- 97.80 yesterday, and up to 98.06 today. What's happening?? Anyone with any experience on this, greatly greatly appreciated!
