what is going on with me?! (kinda long)

now I know that you all aren't doctors, but ive gone to about 4 different doctors and it's just a mystery. so since my last sexual encounter, i've had 2 periods. i'm on the pill. okay. here it begins. basically it's a week after my period, so the first row of my BC. on the second day, i started having small burning like cramps and that alarmed me. i took a test, negative. like immediate negative. i haven't been able to sleep plus a pregnancy scare doesn't help so my anxiety has been up a bit. i was told i had a kidney stone that was 4mm and may not move on it's own, cool okay. i was constipated last month as well! like, couldn't go at all and had to find out by x-rays. i have had waves of nausea and the other day i didn't eat from 4 pm to the next morning. today i feel... semi fine. i still have cramping. i've noticed that i'm drinking so much water but i'm still thirsty. the last doctor i went to ran all these tests and i'm waiting to see if i have h. pylori. it's OBVIOUS that i'm not pregnant but i am CONSTANTLY bloated. like my stomach muscles feel sort of hard. i cant tell if it's just my stomach muscles but they feel hard. i just don't know what else to think. has anyone dealt with h. pylori before? the wait is killing me and i keep getting to my head about it. oh and to top it off, no sti's, no yeast, nothing. i'm so frustrated. i've cried so much bc at times i am in pain and i'm so scared ☹️

i also know i'm not because my breasts don't hurt, but i haven't had consistent discharge and that's WEIRD especially being on the pill....
