I would think it was EWCM - if it is stretchy that it what is it. Sounds like the TCM is working.

I remember I went to the Osteo for help with my cycle because I hadn't had one in a while and oh boy - did I get a lot of EWCM after that and then AF visited two weeks later. Having lots might have something to do with not having had AF visit for a while.

Good luck with it all,
