Considering IVF

After 2.5 years of TTC #1, pregnant for the first time in November and a miscarriage on Christmas Day. I think it’s time to start IVF. Going to do an information session but can any give me any personal experience as I understand the process but how it is during the stims, is the retrieval quite painful as I have the option to do it under sedation but don’t want to put more stress on my body if I don’t have to. Is fresh or frozen better or does it not matter? Any advice at all..
