Egg Retrieval Advice/Tips!!

Sue
Currently on day 11 of STIMS for my first <a href="https://glowing.com/glow-fertility-program">IVF</a>. Will be doing trigger shot(Lupron) tonight for a ER scheduled on 8/23. RE counted 33 follicules!! Although I'm excited about this, I am fearing OHSS! Heard lots of stories of women experiencing pain/ extreme discomfort after ER. Wondering if anyone has any advice/tips going in? What to expect? Stories of their experiences? 
I would appreciate it:) Thanks! Baby dust to all!
