I've been tracking my bbt for about 4 months now.. normally it's pretty legit and is just about predictable what the next day will be.. I have never seen this before, especially how long the OPKs stayed positive. There was no question if they were positive or not.. the first line was very dark, very quick. It finally turned to negative yesterday. Anybody have any idea what's going on with my temps tho??? TIA! Btw no sickness, extra stress or anything. Taken about the same time every morning. Plus or minus about 10 minutes.
