Thanks ladies, I ended up talking to mum about it and I feel so much better now. She made some great points and I feel more at peace with how things are going. At the end of the day we want a family. How that family is formed doesn't matter.
I have everything crossed that our little 'bean' will stick around (so does mum now she is so freaking excited) and then I will stim again for number 2. If it doesn't work out then we will continue with DP's embies knowing we gave it a go and that's more than good enough for me.
If our little bean is not to be then we will keep going with DP's beautiful little embies until we get our bubba and then go on again to stim me for number 2.
We just need to keep our fingers crossed that we can get our hands on more of our donors sperm.
@Boxergirl mum is the only one that knows now and it will stay that way for that exact reason. We don't want the heartache of having to tell everyone.
