Cm question tmi

I took opks this month and got my surge 6 days ago. My cm wasn't exactly where I wanted it to be so we used preseed. Yesterday evening I check my cm and there was an abundance and it stretched as ewcm would but it was very visibly white. Anyone have a clue what's going on or what it could be? I took an opk just for the heck of it after I noticed it that way and it was ghost white lol ..... I've never noticed my cm this way- meaning lotiony but incredibly stretchy. Any insight is appreciated! Thanks!

I posted this on a couple other boards- just trying to get someone to answer... please don't be upset if you see this on another board also
