@ParksAndRecreation if I were you and if I had the option I would go for two....yes it is scary with the possibility of twins, but like you say there may not be another chance later, and you would have your family complete in one go.
My protocol only changed this time in so much as I was on much higher doses (the highest) of stims: went from 300 to 450. Everything else was identical.
I really really hope mine hold on too but I am kind of looking at others options to protect myself from what the statistics of attrition would tell me is the inevitable disappointment on Saturday.
We already have one child and that is a blessing. Just have to focus on that. Thinking of other things to concentrate on and aim for in life that are non-family related. Like getting super-fit and healthy. Going vegan. Getting our own house and making it nice (we're still renting...) Sacking off work and going part-time. Or getting another job/career altogether as I am so sick of working all hours and feeling no appreciation or benefit.... those are my thoughts at the moment anyway.
I would have considered adoption after this ivf (advised not to try another ivf after this one unless outcomes such as fertilisation rates are better, which they are not) but my partner would need a lot of convincing. His heart is not in having another child like mine is - of course he would love one, but only to make me happy and because he knows it's what I want - and I think this would come through in the interviews if we went for adoption. His lack of enthusiasm would show through and we would fail - again - so it's prob a no-go.
So I am looking at moving forwards as a one child family and all that that entails - of which there are many positives, e.g. more money, more holidays, more attention for that child - from now on.
