So sorry that i just saw your post. usually, they will do an u/S before ET and also may retrieve earlier than 33 hours. They always do for me. E2 that high is great for the number of follicles you have. I once had 15 eggs with just an e2 of 915 and it dropped to 715 after trigger and still went on to have my DD. SO have faith and wishing you good luck.
