Amh drastic drop

Hi,

I just turned 35 at the beginning of this year and went to a RE since we have been ttc for almost a year. What I was surprised by was the amh dropped from June of last year from 1.94 to 0.88 in March of this year, can it just become less than half in 9 months?? I have a follow up with RE but that’s later next month. AFC was 15. Does it make sense to get it retested?? Is amh of 0.88 really low .. have been a little low since I found this out..:(, the RE said it was upto us to go for

<a href="https://glowing.com/glow-fertility-program">IUI</a> or <a href="https://glowing.com/glow-fertility-program">IVF</a> given the Low AMH would going directly for <a href="https://glowing.com/glow-fertility-program">IVF</a>

make sense? Thank you..
