Losing hope

Angela • 34 years old. I have one amazing little boy who we prayed and waited for 4 years for! He is an IVF baby! Trying for #2!
Do you ever wonder if you CAN get pregnant? I've been trying for 18months and never have had anything happen. I ovulate and have my period but that's all that happens. I have open tubes, everything looks fine. What if it just won't happen?!
