12 follicles

Went in for my first monitoring US today and I have 12 follies. 8 on my right and 4 on my left. Only 5 on the left are over 7 (3 are over 10) and only 2 are over 7 on the left (1 is over 10). My E2 was 793. I'm not sure if those are good numbers or not... can anyone lend any insight? I go back on Sunday for another Ultrasound. After looking at the stats, I'm concerned about how many embryos we will actually be able to get, when I know the chances of all embies making it to a 5 day blast is slim, based on the odds for most people.  A little of my history - I'm 34 and have sub normal AMH so I'm on an antagonist protocol. Just started the centrotide tonight. My DH has some sperm issues, so that's making me even less optimistic 😔
