Unsure pregnancy *tmi* HELP?!?!

So April 28th I noticed a pink light discharge it increased a little and the next day I was able to fill one tampon, but than after that for the next 3 days I was spotting brownish slightly red and it kept getting lighter each day with a little bit of cm, But my period wasnt supposed to start until may 2nd, I’m normally heavy around 4-6 tampons a day but I this was super light like only needed a pantyliner, here in the last week I’ve noticed being lightheaded continued white cm headaches, cramps, and backaches from 9 DPO still till this day. sense of smell has changed and taste, I have gas, constipation, and minor heartburn, noticed nausea loss of appetite weird considering I have a fast metabolism, and severe dehydration, unusual shortness of breathe just picking up dog toys, i’ve been tired but I can’t sleep takes me forever too, dizziness, getting up to fast I have to lean against a wall, crying has just started. And increased cm like today before I got in the shower their was a jelly like blob insane amount I’ve never had before white and clear mostly clear like a pinch of brown, and a stuffy nose right when I wake up EVERY morning, and my cramps rn or mainly near the pelvic areas, but I failed 2 HPTs and I’m 19-20 DPO. help please?!?!
