Confused about opks

Sherri

I am on cd 11 and still have very low ok results but cm looks like sticky stretchy egg white the one time I got peak I was working 6:30-3:30 and was able to get home and test by 4:00 now I work til four and usually test by 5 and can't see to catch my peak. Should I take tests to work and test before I come home?
