I was 34 when I got a referral from my Ob to start IVF (my Ob and the IVF Dr are in the same office).

By the time I then had all the necessary testing done (including exploratory surgery to check all my insides seemed fine) it was almost another 12 months before I had my first full IVF cycle. So I was 35 at that stage and didn't successfully fall pregnant until I had undergone my 3 embryo transfer cycle (which took about 4 months in total) so I was 36 when my DD was born.

At your age I would be asking for a referral as by the time you 'start' the process you would be in your 40's and then things start to change in terms of success rates etc.

Good luck with your journey
