Glow originally said af was due on April 2.. No show..  Then it changed to today..Ovia another app says af was due April 4..No show... I went to log today on glow answered the question did af show today I clicked no, now glow says the April 14.. Urggggg!! What in the world! I logged all the same info in all apps I have 3 by the way.. Getting all different dates for af.. I give up!!!!!! Fertility friend says April 10th.. I'm so done.. Has anyone experienced this?
