Opinions please

So at my ovulation check the other day I only produced one mature egg this month. The past few months it’s been between 1-3, but never over 3 mature eggs. I overthink things and just want opinions on if this is normal, very low, etc. I take letrozole, do the trigger shot, I’m only 28, and I’m not getting anywhere. I’ve been way more down about it this month, so I just need opinions/advice.
