What a lovely support you are for your sister!! I wish her all the best and hoping she doesn't need IVF. I was 23 when we found out we needed Ivf and when we started, it was very hard but the positive is, time is on our side which sadly a lot of ladies don't have. IVF is luck of the draw unfortunately, some ppl fall pregnant first go and some ppl take a while. It took us 3 stim cycles, 6 transfers and 1 year of IVF to fall pregnant, but my daughter was worth every minute of it. I jhave everything crossed for her.
