Glow says period is due 10/23, pink pad says 10/20 and another app says 10/18. Glow was behind on the ovulation date by one day. I ovulated on the last day of my fertile period. I am soooo anxious to know already. 5/6 dpo is way too early for a real answer. Agh I hate this waiting game. I will try to hold out till Monday to test and then the 23 which is glows date. Anyone else period due 10/23????
