What Does Mucous Look Like Before Menstruation Can You Mucous Plug Look Whitish/yellow And Sticky?

Can you mucous plug look whitish/yellow and sticky? - what does mucous look like before menstruation

I am 37 w 5 days and yesterday and today I know a very strong increase in this type of flow that normally does not, of course, in general, but is now yellow-n It is not clear or tinted with blood, as I read it, and 2 tablespoons each. This happened when I went to the toilet, and now I feel more will come, but I do not see until I clean. Is this my mucus plug or is the increased secretion? I reiterate that my resignation was not the color before.
