I have been using another app to track my cycles for a while, and it’s usually spot on. This month today is day 3 late. If I’m ever late, it’s only by half a day. Like af will arrive during the day instead of the night before. All the FRER tests are negative, and I got a vvvfl on a blue dye clear blue a few days ago that I chalked up to evap and moved on. I’m just not sure what is going on. I have 3 day cycles so if af doesn’t arrive by the end of the day then I’ve missed an entire cycle. I have had no pms, no signs of af at all. Is there still a chance that maybe the tests just aren’t detecting it yet? And if I don’t have one this month, then I’m out until my next cycle. I’ve never just missed a period. Usually once I get a negative test and know that I’m out i start right on time.
