I lost my mucous plug about 2 weeks ago.
It was slight over 3 days (all once off occurances).
THe first 2 days were similar to what you describe like a yellow jelly but had streaks of bright red blood in it and on the third day it was a big blob (about 50mL) of what i can only describe as dark chocolate yogo! (yes the dessert) all at once nice and clean... nothing since then and still waiting for bub! lol
