Ovulation test

autum • 27 country girl 🌻 One miscarriage and one chemical TTC hoping for a rainbow baby soon!

Here is my ovulation tests this past week and I am always regular and always have ovulation on day 14 but this month is weird. I am not sure if I ovulated or not but I am confused. Has this happen to anyone? It was progressing at first but then got lighter then darker and lighter again and today is cycle day 19 and it looks pretty dark still.
