Usually when I ovulate I get really sore boobs and pain and I can usually guess when to test due to that but this month i tested Monday and got neg I tested Tuesday got a slight line but not a positive I couldn't test on Wednesday due to running out of tests and forgetting to pick some up and when I tested Thursday still faint line and that's all I've had since and today no line at all so either it happened the day I didn't test or I've not ovulated but today my breasts are swollen and sore but I'm definitely not ovulating does anyone no why this would happen
