Q re discharge while ttc

Hello all! Quick question here for those who don't mind a little
squick....

Background: I'm ttc #1, and have been for about 2 years. We're
working with an RE, I've done all the usual, have TCOYF, know about
cervical mucus, etc etc.

However, this month (we're trying old fashioned this month), I had a
very strange occcurance. In a visit to the bathroom, I wiped and found
a rather large chunk of goo on the t.p., almost like snot in
consistency. Not stretchable and clear like EWCM. Just one very large
"clump" that was almost jello-like in consistency. Cloudy, with a
tinge of pink.

This was post O I believe, but too soon for implantation I think? At
any rate, never had this before. I found *one* reference on the web to
all women having a "mucus plug" like thing in the LP of the cycle.
Almost everything else dealt with the famous "mucus plug" of late
pregnancy.

Anyone experience anything similar? Could it be a pg sign?

Thanks!
