Mel, try not to lose hope just yet. I don't know the specifics of your situation, but I can see from your signature that you've had one IVF/ICSI which resulted in a pregnancy (and miscarriage) and one failed FET. Practically speaking (and practical is all that I do) it's still very early days. I understand that your bloke has the varicocele issue (I now believe that I have too, but that's another story) but clearly his sperm was capable of fertilising your egg on the first IVF/ICSI cycle. So I imagine it would be too early to be considering donors. I gather that these days with the increasing uptake of ICSI, donors are generally only used in cases of azoospermia - as long as there is sperm there they seem to be able to work wonders with them.

As for the failed FET, well consider how many people actually do fertilise naturally each month but the embryo does not implant and they don't even know it. Before long, one does implant and bob's your cousin's aunt you are pregnant. A friend of DW's had two m/cs (natural conception) before her third pregnancy, which seems to be going ok thus far.

Just try and stay on top of it. I'd reckon the signs are looking pretty good for you both.
