Any ideas?

Hey y’all! This last week I haven’t been feeling myself. I have been very emotional (literally wanting to cry at everything), having light doozy spells, very thirsty, bloating, nauseous and almost threw up a few times, and cramping here and there. Literally 5 minutes ago I when to bathroom and when I wiped (this will be TMI) there was what looked like literal congealed discharge and it was VERY stretchy. I took a test about 2 weeks ago and it came back negative. I’m 21 so idk if it’s just hormone changes or I could be pregnant! Help!
