Clomid this cycle or wait?

Le

I'm 39 (40 in Dec). We've been ttc since April. Doing all the right things. My hormone levels are where they should be throughout cycle. I'm ovulating (confirmed with blood work). My cycles at long. Average 37days but can be up to 44days.

My OBGYN said we can either try one or two more cycles without Clomid or start Clomid this cycle. We have to decide by Monday.

What are your thoughts? What should I take into consideration?
