need help!!

Not sure if this is the place too come but could this be a possible cryptic pregnancy or another health problem that is causing my belly to look like this? This is it over the past week, last week there was just little bloating towards the pelvic area, i am generally a tiny person with no tummy that's why i've noticed the shape so quickly. i've started bleeding around a week before my periods due but it has no smell, and is really bright sometimes or brown but it has been really heavy, sometimes little clots, which has me confused. No vomiting but there is nausea when i first wake up and start moving for the day, I have had bad headaches, i keep feeling a tug feeling in my stomach here and there, i've had cramps every few days i feel like, back aches almost everyday, my veins are showing so obviously right now it's crazy like everywhere, moments where i feel like there's not enough room for my boobs and stomach at once like im in a tight space almost idrk how to describe, random pains come in my buttocks here and there, random stomach growls even when i'm not hungry, have felt exhausted, and random muscle spasms when laying down for the night, but i haven't gained any weight, pregnancy tests have all been negative, including home, urine, and blood. but i also got random UTI. i'm just not sure what could be going on i don't know if it could be a missed pregnancy or if there is something else going on with me.

Lmk please.
