Considering IVF

Tiffany
My husband and I are considering IVF
Background: 
I'm 25 years old. After my last (2nd)  pregnancy I had my tubes tied. Because I was scared of having postpartum depression again like I did with my first child. I didn't think I would want anymore because I never wanted to feel like that again. But after my second child I didn't have pospartum depression. Now my second child is almost two and we have discussed IVF.
I have so many questions. And I am afraid it might not work. Please anyone stories advice....
