Well, we can't really know from here. But, the deal is, pregnancy trackers are great to help record what is happening and make a 'best guess' but aren't always accurate. they aren't measuring hormones to find out your actual ovulation time, etc. So, take when they say you should start your period or ovulate seriously but not as the absolute last word on the matter. Women ARE late all the time for a variety of reasons from changes in routine, stress, illness, weight gain or loss, or just a blip in the hormonal radar. Things like being moist, etc. are not helpful to knowing if you are pregnant. Most women have no symptoms that early on. And discharge is always deceiving and not good to predict things. The only way to really know is to take a home pregnancy test. You can wait until you are a full week late, use your first mornings urine and read the test stick at the right time (don't let it sit too long, evap lines appear and confuse women). Likely though . . . you are just late. After you test if your period doesn't show, let us know!
