On the verge of giving up..

We have been trying for a year with more and more set backs every month. I know to many that doesn't seem like long. I'm 21 all of my friends are on their 2nd or 3rd child and I cannot get pregnant. We have been to fertility doctors and havw tried <a href="https://glowing.com/glow-fertility-program">iui</a> and injections. Nothing seems to be working.... the amount of money we have spent and mental strain it has our on me is insane. I wanna quit so bad but then it will never happen.
