We were nervous as hell but got our questions sorted and waited for the call. We asked everything we wanted to and more, he answered everything to our satisfaction and asked us lots of questions too.
Before the phone call he sent us a donor contract to read over that we must agree to before he meets us. We read through it all and are really happy with it, he's been a donor at a clinic for a while (for medical research) and has undergone all of the relevant counselling etc that prepares him for being a donor. The contract basically states that we will not come after him for anything, we will have healthy lifestyles in order to promote a healthy pregnancy and raise our child/children with their wellbeing in mind.
We're really happy with him and a few days later asked him to be our donor with a view to having a donation at some point within the next week.
In the end, he could only do Thursday or Friday because he had a commitment to another couple who are trying for a sibling with him and he wont donate to more than one couple/person within 48 hours. This wasn't ideal for us as my wife was looking at ovulating on Wednesday but we it could have worked. When it came down to it, the only night i had off work was Thursday and my wifes ovulation delayed itself until Thursday so it was perfect!
We're now on 13dpo and there's weird stuff going on, fingers crossed it's good weird stuff but we just don't know.
