Ovulation days

Rachel • After 4 years and 4 miscarriages. I gave birth to our rainbow baby, Olivia, in January 2016. God is good. Since Olivia we’ve had 1 ectopic and 1 miscarriage hoping one day we will have another child like Olivia so she has a sibling.
Hi glow, so the app has told me my peak day was yesterday but I didn't get a 'peak' on my opk. So I haven't as yet peaked. When will the app match up with my opk? (I log the data everyday)
