While every person is indeed different with how their body will respond to the IVF egg retrieval process, most doctors will warn patients that day 3 and 4 post-op are usually the worst. From my experience, this was spot on. I literally couldn't move. I sat in a chair, feet up with ice packs and heating pads rotating on my abdomen. But, I've had clients who felt totally fine, just some minor cramping on these days. So, rest assured, everyone is totally individualized! Hopefully you will escape the pain too!
