I’ve just started testing to see if my ovulation period is matching with the app. My period was 5 days late and my ovulation started yesterday this was the first test I took yesterday it is actually darker than todays turned out. So I’m confused and not sure how to really judge by these. My husband and I are trying to conceive after having a miscarriage last December. Any help would be appreciated.
