Endometriosis

Please can anyone help!
I got diagnosed with mild endometriosis this year in January, I am 21 years old. unfortunately they couldn't burn it away as its on my bladder. For three years now me and my boyfriend haven't been using anything and still haven't fallen pregnant... I wouldn't say we have been trying, but at the same time I wouldn't say we have been careful.. I'm worried to think will I ever fall pregnant and will the only chance be through <a href="https://glowing.com/glow-fertility-program">IVF</a> :( has anyone else been down this road?
