Started Letrozole - No Ovulation?

Hi everyone,

I’m 32 and recently started my letrozole journey.

I’m currently on Day16 and still have no ovulated. I’ve been tracking using OPKs but only saw 1 rise on the morning of Day12 and was low again the next day.

My natural cycles are typically are typically quite long 46+ days… anyone on the same boat and had any success with letrozole?
