Ovulation test question...

Genni • BFP after 2 years, 1 MC, fertility treatments and 2 IUI's... So excited 😃 due 2/15/17
Morning... Quick question. This is my first month using Glow, and although it's been straightforward so far, today I am quite confused... I got my positive smiley face ovulation test this past Saturday and recorded everything etc. Today (Monday) Glow is telling me to test for ovulation again via my daily important task tip... I was under the impression that once you get a positive there is no need to keep testing so I'm a bit mystified. Any insights would be helpful. Am I missing something? Don't want to get this wrong. Been TTC for 7 months without opk and tracking and no luck, so Glow is my new approach. Hoping it works! Thanks in advance! :)
