Ladies! (TMI) but need help! What is this!

Hi ladies - so I need your help! As you can see in my picture, this glob was literally dangling after going to the BR this morning. It looks like EWCM, however, based on my opks + temping, I can confirm O occurred CD13 putting me at 4 DPO today. (Added charts for visuals as well). Let me know your thoughts!
