CM help!

Sa
Hi everyone! So, I'm 10 dpo, period due in 5 days and this morning a had a huge blob of CM. It kinda looked like EWCM, but more gelatinous and very very stretchy. It was on the TP when I wiped and it stretched more in like a window manner than a string (if that makes any sense). My cervix is extremely high, can't even reach it so I don't know how soft/hard it is. Has anyone else experienced this? Was it AF coming, late ovulation, or ended in a BFP? Thank you all!
