Happy be-lated Birthday!
I hope you did something nice to celebrate! 
I had my one and only son when I was 31 and I never gave it much thought about being lucky enough to have someone to TTC a DD with..but here I am knowing that I put an age limit on that too if I was to ever get lucky and I have gone past that one....I was hoping that I would have my last baby by the age of 38 and here I am...38 and not pregnant or even trying yet!
Don't worry yourself! You have time and I think it's best you TTC when you are ready...not because you think your running out of time cause your not! Best of luck to you and you will certainly have plenty of us cheering you on when you start!!
