Ivf 🙉. Scareddddd

Hey ladies 40 yr old ttc 3 years went to an appt with a fertility specialist the other day he said I should go straight for ivf. I tried one iui and it failed with my gyn. Was hoping to be able to do iui n shots again but he's jumping right over that cuz of my age. So now I'm scared out of my mind and hoping for a miracle so I don't have to go through with this. Anyone my age or older conceive naturally? How????????  Thank you
