Wondering how big the mucus plug usually is, wonderin if mine is normal.

So yesterday was my due date, I'm pretty sure my mucus plug came out cause when I wiped there was a long stringy mucus-like glob that was mostly clear colored but with a slightly yellow or brownish tint. I even looked up pics online & it was identical to some of the pics I found. I assumed that was it & it was over & the plug was gone now, but the whole rest of the day every time I wipes down there, there was more of the same stuff, & even again into the following morning now I still have that stuff coming out when I wipe. All together that seems like a whole lotta mucus! So is the mucus plug actually just alot bigger than I thought, or do u think what I'm experiencing isn't the plug but somethin else? I'm hoping this isn't something I should be worried about :( thank u
