Thoughts please ladies

So I am currently 5 days late which NEVER happens. I am like serious clock work when it comes to my period. Two weeks ago roughly a big big glob of mucus came out (just one time). Then last night a big sting of music came down so I grabbed it and it was a huge glob of mucus. (As shown in pic) I have taken a few tests and they say negative but could I still be pregnant?
