Hi everyone, im a bit confused now with OPK tests, this is my first month ttc. On saturday i got my first flashing smiley and same yesterday and today but when i do a cheap opk test the line is still very faint. just wondering how long it usually takes to get fixed smiley as i thought it should have been today or maybe tomorrow and not sure why the cheap opk test i took this afternoon the line has faded alot (held on 2 hours before testing)
