High FSH in early 30's/Can FSH fluctuate?

Hello,

I've been TTC#2 for 14 months with no BFP. I got pg right away with #1. I just got my FSH back and it was 17. I have had two previous tests for FSH over the last 9 months which were in the normal range (6-9). Does anyone know if FSH can fluctuate?

Also, I am wondering if anyone else is in their early 30's with high FSH and what your RE is doing for you. They've put me on Femara this cycle and will trigger when the follie is mature. They've also recommended DHEA three times per day - that is supposed to help some women lower FSH.

Any advice/experience would be helpful. I am trying to gather as much info on this as possible.

Thanks!

Angela
