Extremely high FSH

Keren

I just turned 41 and trying for our 3rd child for a year now. We have 2 sons: 3 years old and 2 years old. I've had 1 miscarriage and one more (not confirmed). Last month my FSH was 8.4 and this month it is 37.7!!!!! Going to get new blood work done in a few days and back to the doctor to discuss next steps. Anyone had very high FSH come down? Could this be a result of stress, anything else?
