Ok ladies, I need help!

Two days ago, I got a peak result on the clear blue digital OPT 2 days ago. With this test, once you get a peak, the result stays on for 48 hours then the test goes blank again. Well this morning just out of curiosity I took another test using the same moniter and got another peak. I am sure the last peak was accurate because my BBT rose this morning by a whole point. What can this new peak result mean? Why would I get two? Thanks in advance for all help.
