PLEASE RESPOND IF HAVE HAD OR KNOW ANYTHING ABOUT

I am 7dpo af due dec 6-8..

I went out town this morning and couldn't get to a bathroom when I got home to pee ( finally, had to go) I had a glob of snotty looking mucus mixed with creamy white when I wiped?! I have never had anything like this and now I am cramping every low and low part of back?! ANY IDEAS?
