Temp dropped below cover line yesterday and AF due today. I've been spotting for the past few days and having slight pain on my side (not the usual cramps I would get for AF) but I do feel like it's coming because of the spotting (I usually experience spotting days before AF comes) I'm now 14 dpo and got a BFN so I know I'm out this month. But what I want to know is why did I have a rise in my temperature again this morning? Shouldn't it stay below the cover line? Anyone else experienced this or might know?
