24, married, but thinking about having a hysterectomy

I have always wanted a family. Our unexplained infertility kills me everyday, we have gone through so many fertility treatments that have failed. We have been ttc for 3 years. The thing is, I am in constant pain that is not all in my bad. Excruciating, heavy periods. Bad cramps during bowels (especially during period) Had a hysteroscopy that removed three polyps but the pain remained. 7 months later, nothing has changed and I’m still not pregnant. To have constant pressure/pain on my ovaries and uterus everyday of every cycle is not an ideal way to go through days. We both want children, but I also want to feel good. What do I do? Is it selfish of me to consider a hysterectomy?
