Ovulation Strips! Advice!๐Ÿ˜Š

This is my second month TTC, last month I didn't use ovulation strips. This month I have used them! My cycle is normally 30-31 days long! These test are 6, 7, 9 & 10 days past my period! Witch is day 12, 13, 15 & 16 of my cycle. Will this line get any darker or am I ovulating now? Should I still take the tests until it fades? Am I doing things right?๐Ÿ‘ถ๐Ÿปโœจ๐Ÿ’› Baby dust to everyone
