hi ladies! so I've been testing since Friday since my app said my fertile window was the 9th through the 15th. I have not had a positive yet, but today my test line was much lighter than it had been so far. does that mean I've missed my ovulation day, or does the test color not matter unless it's darker than the control? It just seems weird that it would be lighter than it was before. and after I entered that info my app shifted my fertile window to last week..??? I feel like I'm never going to get pregnant 😣
