Quick run down, Af was due 27th according to my <a href="https://play.google.com/store/apps/details?id=com.glow.android">glow app</a>, I haven't gotten it,  it's been 4 days now no af........been tracking for almost 4 months now and usually it falls on the "predicted" period days that app shows on the calendar.  Is it too early for me to test or should I just wait? Also been tracking my temps. Consistently range between 98.4-98.6...
