TMI post graphic words

There was a long thick white/yellowish glob of discharge hanging out my vagina while using the bathroom it scared the crap out of me now I’m trying to figure out why it’s there ! It has no smell at all and I get checked quite often for stds I don’t have a infection that I know of but can somebody help me figure out what it is I’m not ovulating either I have a picture as well my cycle analysis is 27 days
