I waited until getting married & nothing

I am 43 and was married 5 years ago. I was very cautious because I wanted to be married and have kids!! Why did I wait, now we have tried iVF IUI AND NOW THINKING ABOUT DONORS! I just can’t understand why I’m not getting pregnant! The doctors are saying my eggs have no quality now but I have a boat load of eggs. No PCOS just a small cyst I has to remove. My husband has two kids and I have none. Sometimes I get so emotional I just want to leave this earth. It hurts like crazy. I’m a women and can’t get pregnant isn’t that why I was created. Everyone around me has kids that I have helped raised but I can’t get pregnant. What’s wrong with me.
