Hi, can I join please? 
Like you, OP, I'm 35 and like you, I'm a bit concerned about age too. I have a thread running around this actually and have to say, majority of posters were 35 plus when TTC and most didn't have big issues.
We're a ss couple, so require some swimmers
We were probably going to start trying early next year using a donor- Jan/Feb time, whilst I load up on vitamins and get myself a bit healthier, although I'm not going to be too strict about it, as I've heard so many stories of women struggling TTC, do everything "right", no alcohol, no sugar...no fun
and can't conceive, but when they relax and don't try anymore, they get pregnant! Don't get me wrong, I still think it's a good idea to get fit and healthy, but not in an obsessive way..iyswim.
I have fertility tests in a couple of months (earliest appointment I could get!) and we shall take it from there- I.e, do we give IUI a go or should we go straight to IVF.
What supplements is everyone taking in preparation? I hear 3 months is a good amount of time to be taking these before
TTC, as that's how long your body takes to generate more eggs. It's been about a month for me. I'm currently taking folic acid, magnesium and ubiquinol. Was thinking I should add vitamin c and zinc, but I don't want to end up rattling 😅
Anyway, hello to all my fellow soon to be TTCers 🙋♀️
