Spotting and bright red bleeding at 6 weeks??

I am around 6 weeks pregnant and do not go to the doctor for another week and a half. Yesterday I started having some cramping, I would consider what I had mild cramping. Today I woke up with cramps worse. They felt exactly like my period cramps feel. The cramps did seem to go away after taking Tylenol. I have been experiencing on and off spotting today and twice I have had bright red blood mixed with some clear stretchy discharge. The bright red blood only showed when I wiped. I have worn a liner all day and it still only shows some spotting. Has anyone else experienced some bright red blood but not miscarried?
