I think I had a bad experience with ER so don't let me scare anyone.
I had:
30 follicles
18 mature eggs
11 fertilized
5 embryo's made it to 5-day blast
I felt like HELL after ER, I was really nauseous & in pain. But I really think that is because I had so many follicles (which reeked havoc on my hormone levels). It took me about 4-5 days to feel like myself again. I had pretty bad OHSS --I attached pics from my journal below. My hormones were so whacked they wouldn't let me do a fresh transfer. I just think I had a really bad experience because everyone else's seems to go seamlessly compared to mine.
