Are you in an area where you could join a temp agency which would get you work? I find it's very flexible for your appt's etc and you won't have the stress of telling new employers about the time off.
That is another option we are considering, well more of a back up plan!
And if financially you are also unsure, it may be worth considering that by waiting an extra 7-8 weeks (oh boy help us that the end of the year is only 14 odd weeks away ) it will put you into the new year and the start of the safety net, so if you require more than one cycle you will get that benefit and not be as much out of pocket.
that is also another reason for waiting. I have to keep reminding myself that it may take more than one go before something happens.
Thanks for the responses, there are so many reasons to wait and at the same time so many reasons to start right away, so we have some thinking to do!
