Hi,
I am 36 now and have a 3 year old daughter who was conceived with no help. We then tried for a year and nothing. We tried Clomid first and then Clomid and IUI and still nothing. All of my tests cam back normal except I have one blocked tube which was there when we conceived our daughter 3 years ago. So we decided to just go straight to IVF which would give us the best chance. I produced 39 eggs and 27 fertilized. I was worried about age to but it is not that big of a deal at 35. I am now 16 weeks pregnant. So it can happen, just don't give up hope and stay positive. I know sonetimes it is easier said then done. There are so many stories on here with so many women of different age groups getting pregnant. Good luck! It will happen.
I am 35 and I got my first bfp this year. IVF definitely gives you a better chance of success although trying injectables+IUI before moving to ivf may be a good way to proceed since it's less invasive than ivf. For me, only ivf worked but I have infertility issues that make IUIs not very effective.
Good luck to you!
