Hi guys,

Thanks for your replies. I agree about wanting to get the embies to the Blastocyst stage because it's like survial of the fittest! I was reading the book they gave me yesterday and apparently if they have more than 6 embroyos at day 2 or 3 then they will try for a blastocyst, otherwise you get a 2 or 3 day embie... which is fair enough for now being my first cycle, I have a long way to go before I worry too much about these things.... I was just curious because the blastocyst stage makes so much more sense to me.. And I am over 35 so I do have the option to go 2 embies (which is what my DH would like) but I think the risk is too high... for now anyway... Thanks heaps for your replies.... I have an ultrasound tomorrow, it was brought forward because my blood tests came back with a high level of hormones, not a great thing I imagine but they said I'll either be cancelled, change in my stims or change my EPU to Friday... fingers crossed I dont get cancelled... Thanks again x
