I am 35 years. First cycle two cycle in South Africa with no result, third IVF in Germany. Hyperstimulated terribly and had to receive tranfusions, 22 eggs retrieved, 11 fertilised, 3 (thats the law in Germany) transferred in May, 8 frozen. 12 day after transfer started bleeding and my period came. Will probably have the next tranfer with my next cycle. I dont know what I did wrong but until I run out of frozen embryos ( and money) will keep trying.
