Egg retrieval scheduled already!

Tonight is stims night 8 and I just got an email that my ER is scheduled for Sunday at 9 am. I’m doing a lupron trigger and a freeze all cycle due to being at risk for OHSS. Any tips? I’m so nervous number 1 about being put to sleep and number 2 for getting ohss and of course how many eggs we get. They are taking all precautions though. So happy I didn’t have to do the 12 days. I’m so uncomfortable!
