Hey Possums, might be a bit late for advice but I will throw in my two cents...if I were you that is with your age and your histroy, I wouldn't stress over a few months. I know you might feel 'you are losing precious time' hence the pressure of get going but the truth is, there won't make huge difference on your reporductive system in the matter of a few months, but a break with an overseas holiday can do world of good.

Sounds like you and DH are really keen to have a break from this but only due to the 'clock is ticking' feeling responsible of keep going. Well, don't. Go and enjoy yourself and don't even think about it, have an overseas holiday and make the most of it. I still think you have a great chance of having a natural conception, the reason for your past m/c is now being addressed, so that also adding the chance of a complete success. Even if it didn't happen, then you will be in a much better mindset to get onto the IVF train when you are ready.

All the best hun and you totally deserve a nice break!
