endometriosis? pls help

hi! so i’m already in the process of getting investigated for endometriosis but i just want to get an second non-medical opinion.

i’m 21, not sexually active or pregnant and have pcos. i had my period since 10 years old and it’s been hell. before my period in september, i went 5 months without one and when i got it, it was heavy like gushing, having to change pads every hour and the pain was worse. the pain i have is sharp right side pelvic pain that goes into my back, radiating down to my leg and going deep inside my vagina. on my period, it’s so much worse but i’ve been having these pains everyday.

my doctor has put me on the mini pill, noriday, and i had my on the 5th october and it has been very heavy, changing pads every hour, vomiting and unable to do anything. i have been also passing huge blood clots in the size of a golf ball and hurts to pass. period has finished on saturday but im still feeling in pain and feeling dizzy, have a headache and tired. i’m getting tested for iron deficiency but i just want to know if anyone has experienced this with endometriosis and what else i could do? pain relief and heat relief doesn’t help
