TMI: cervical mucus fertile?!

Hi ladies- can't get down to the store for an opk. Had a positive opk yesterday afternoon but haven't tested since then, had a bunch of cervical mucus since Friday, and it's stretchy, clear and basically like Raw egg white. Is this fertile CM? I'm fairly new to charting etc. so could do with the help! Example in the picture below, there's just a bunch more of it than shown.
