Is this endo ? Please help !!

Hi everyone I am a 22 Female and I’ve been experiencing some symptoms that are concerning to me on and off for about 5 or 6 months.

I am having lower right abdomen pain It has flare ups, the pain comes and goes but a dull heavy ache is always present. When it flares up it is stabbing, shooting, and twisting pain. Does not hurt when you push around it but it hurts with movement or bending or pushing.

I started experiencing it again 11 days ago accompanied with lower right back pain and rarely stabbing pain on my left side of my abdomen. It also rarely stabs me near my belly button too.

My other symptoms this time around are passing lots of gas and right leg pain. I went to the hospital 5 nights ago because I was really concerned about this, they took bloods and urine and they were satisfactory they then felt my stomach and said it wasn’t appendicitis and sent me home with pain killers.

The pain is still there and I cannot sleep on either of side and now I experienced a tiny bit of blood in my urine and I’m freaking out.

(Just some info on my periods in general) My periods are always very heavy and last 7-8 days accompanied with cramps. Some periods I cannot go to work due to how much blood and how weak I feel.

9 months ago for about 6 weeks straight I was bleeding every single day and my period became extremely irregular, I went to my GP and they sent me to a gyno specialist 5 months ago, I had ultrasounds and nothing showed and that was the end of that.

She ruled out PCOS and said the only way to diagnose for endo was a laparoscopy but I heard nothing back since.

I also should I add I have 3 bulging discs in my back and sciatica not sure if that contributes to my symptoms.

Can someone please give me some insights to my symptoms I feel like no one will help me
