Ovarian cyst? Endometriosis? Pill aversion?

Please i am really hoping someone can help.

Hi there

I have been having abdominal pain since dec, and kept thinking i was pregnant, as my symptoms are : swollen sore tender breasts, bloated stomach, horrendous stabbing pain, sometimes like a dull ache, in both sides, where my ovaries are situated...it sometimes goes from side to side almost like i am being sliced! Today for instance it is in my right side of my abdomen and is constant, the only way i can sit is hunched over, now as i am writing it is moving over to the left...I also have constant nausea, am extremely lethargic with very heavy what i can only describe as 'dead' legs, some days i wonder who i am going to lift myself up off of the chair, and have absolutely no energy whatsoever. The pain is so so bad that i just dont know what to do anymore. I am awaiting a TVS at the hospital, but goodness knows when that will come through. I am panicking and working myself into a state. The scary thing is, is that I have never ever suffered with any sort of period pain or anything like that! I only have really a little bit of relief when i am on my period for a few days....I just got blood tests come back clear! I dont know what is going on!!I hope someone can help. Thank you so much for reading x
