Hi, Im in my first cycle on day 2 of my TWW...think this will be the longest 2 weeks of my life! We commenced our IVF journey a couple of months ago but my first transfer was cancelled due to Hyper Stimulation which led to 2 days in hospital. When we arrived this month to have our transfer (2day) we were advised our first embryo didn't survive so they thawed another and it was a 3 cell. Our F then advised us to thaw another to take our chances from 25% to 40%. We had 2 transferred and are now waiting anxiously!! My husband and I do not have infertility problems but he had a vasectomy 3 years ago and we opted for IVF as opposed to vasectomy reversal. Does anyone know the percentage of success rates for twins in an IVF cycle where fertility is not a problem??
