Ovulation and CM , so confused

Mary
So I have been taking the digital  first response ovulation test and it gave a me a positive result on February 17th. I was supposed to get my period March 6th. It is late. Still negative pregnancy tests! But today I was having eggwhite CM which makes a string In between two fingers.  Is it possible I skipped my period and I'm ovulating again ? Can you ovulate with out getting a period ? Or is there a chance I am pregnant ?
