So this possibly a tmi post but I just need someone's thoughts on it!

I am 6 and a bit weeks pregnant with my 3rd and just went to the toilet and wiped away a kind of big amount of mucous.
It was thick and in a clump about the size of a 20cent coin. It was clear and stretchy but I have never had anything like it early on in a pregnancy? It reminded me of a mucous plug minus the blood.
I also then checked my cervix (naughty I know and the first time I have done it since finding out I was preg) and it is very low but seems closed.
I'm not having any pain really just bad stretching pains and niggles in my hips and back.
Hopefully someone can share some wisdom with me or else I'm going to be tossing and turning in bed tonight!
Thanks
