living with Endo and IVF (Adelaide)

I have been suffering with endo for about 6 years it is very sever. I have had a couple of laps and also lost my left ovary. I was sent to IVF fell pregnant straight away (very lucky) I had a baby girl and she is now 10 months and I am loving every minute of being a mummy. BUT When she was 3 months guess what came back yes that damn endo my ovary got to 13cm big I have just had another lap to clean everything up and have to do the whole IVF thing again. I was thinking of having another baby in another 2 years but they don't like my chances, I have 3 frozen eggs left. So my question is to you mummys that have gone through IVF the second time round what are my chances going through the frozen egg cycle?
Im abit nervous about it as I don't have time on my side.
any info would be greatful
I go to the repromed in adelaide.
