First IVf cycle to do it now or wait until 2013?

[MrsA]

Hi, I am not sure where to post this, so please feel free to advise?
I have had a shocking year, in Jan found out was pg for first time after LTTTC only to mc at 6 weeks, then 3 months ago my younger brother passed away at 30.
I don't know if I should just wait until next year and try and relax on my 6 days away in December, or just bite the bullet and do it now to get the first one over and done with. Basically the only thing I havent done is the egg retevale or ET I have done all the injections and supports. I was wondering if any of you ladies would be able to offer some advice
Thanks
