I use clear blue advance ovulation test. Two days ago I received my peak according to the test. Which shows for 48 hours and the instructions say not to test again this cycle. me being me I decided to test again today to see if if was still ovulating. I didn’t read the instructions about not testing again durning this cycle until I had already tested. It said I was low digitally but when I removed the test it still had two pretty dark lines. Has anyone else experienced this, will you still have two lines if your not ovulating?
