K.A.
I was 30 when we started 6 unsuccessful months of Clomid+ IUI before we decided on IVF. It was extrememly stressful (we tried for 3 years to get pregnant on our own- but the entire situation was stressful, as you probably are already experiencing) and hard on our relationship. Nothing like having timed intercourse when you are not in the mood!! However, in the end, worth every effort. We were able to conceive after a 2nd round of IVF, and have a beautiful little girl.
I do know others who have conceived through IUI.
All I can say is hang in there! I know its a rough go, and of course nobody can say "this time its going to work" with a guarantee, but if successful, worth it. And if it doesn't work, you are at the beginning of this journey, and still have options.
I got a little crazy, between the drugs and my already strung out emotions. And it seemed like everyone around me was pregnant! Honest communication between you and your husband, along with your doctor will get you through this.
Good luck!
