Going nuts....

So glow says AF is due 4/11 and then ovia and pink pad say the 4/8....I track on all 3 seeing as glow wiped out all of my previous months when it updated }:l I ovulated 3/27 opk and CM were spot on, now not sure weather to ride it out till 4/11 then test or test at 4/8 and normally I spot 5 days prior to AF and no symptoms other than feeling lethargic and sore boobs for the last 3 days. Any advice would be much appreciated. TIA :D
