Advice

This is my first time putting a post up and I was hoping that if I share my story some of you wonderful people would be able to give me some advice.
Back when I got my first visit from AF I was 10 but it wasn't normal it was very painful 9 years later I was diagnosed with a very bad case of endometriosis which is joining my left ovary uterus and bowel together, I was also told that I have a 4cm cyst inside my left ovary and a 8cm cyst inside my right ovary.
Over the last 10 years I have been on the combined pill, the everyday pill, the injection, the implant, the coil and I've had the prostap injection (for those who don't know, this injection causes an artificial menopause).
I have been told by my doctors and gynocologist that I could be infertile but they won't test me until me and my partner have been trying for a year, they have offered me ivf but where I live I only get one free round and me at the age of 20 and my parter at 24 we can't afford up to £5,000 to try again.
I know some of you may say that we are too young to be trying for a child but I literally get this chance, once I have had a child they will remove everything so I will never have to be in pain again. I don't know what to do if you have any advice please help me x
