please help… i need some reassurance

So i’m 26w5d. I PROM’d with my first at 27w3d. Lost my mucus plug the day before and didn’t really know what it was till after. It was very long and thick. Reminded me of a tampon almost. I’ll post a picture. It will be the first picture.

well, my discharge has been smelling off and i just got this. I dont know if this is just a small bit of a mucus plug or just a chunk of discharge. I need a slight bit of reassurance. I know you can lose it throughout the entire pregnancy but it just makes me very antsy due to previous history of my son coming early.
