Ok so I started testing for O at cycle day 6 bc I usually O earlier than day 14 I have a 26-28 dAy cycle. Day 6 with dollar store test was positive so a little shocked we had intercourse and next day I tested with clear blue digital to see if it was high or peak. The test was low and then low again the next day. We are doing the BD every other day, my AF was 5 days long...Today I could not get the test to read (tried 4test strips)...a little confused ...any ideas or suggestions? Thanks.
