Why are you ttc with IUI?

I am 33 years old and a mother of 2 beautiful children from my ex husband. My oldest is 9 and my youngest is 3 and their father left when I was pregnant with my little one. Shortly after my divorce I met and married the love of my life and we began ttc. After 2 years we were referred to to an infertility clinic and found out that I have high FSH levels and he has a low sperm count. Our Doctor said it was best to go straight to injectables considering our infertility factors and my age. So here we are on our 2nd cycle of IUI and dreaming of our together baby. 😊
