CM question?

Chels

I took an opk first thing this morning. However, I went to the restroom a little while ago and I had this CM which I’ve always thought meant fertile? Has anyone ever experienced fertile CM but a negative opk? I’m only on CD 10 so I’m extremely confused. Any insight? Should I BD tonight anyway? Thank you so much in advance!

Also, I did blur pic as TMI but I’m not sure if it worked.
